• Z580 UEFI boot problem

  Hello everyone,

  I recently bought a Z580 (product number 59362732), provided without a pre-installed operating system. I installed a Crucial SSD (instead of the HARD drive) with success and replaced the DVD drive with disc HARD original.

  After installing Win7Pro and all drivers provided on the SSD (UEFI boot is set to on, SATA AHCI mode prior to installation) I am facing a strange startup problem - it seems not every time, but the laptop often just hangs after the Lenovo logo disappears and restarts itself and, as if he could not find the partition to boot from. However, in the configuration of the BIOS, everything seems normal - it recognizes both of my drives. This problem appears on the two UEFI on and off the start, but strangely, Windows starts without any problem after activating/deactivating the UEFI BIOS Configuration option - it doesn't matter if the activation or deactivation. I have searched for the solution on the Internet but haven't found any solution. Any help would be appreciated.

  Thank you, feki1409

  Hi Zoltan,

  Thanks for your advice in the first place! I tried to update the firmware, but it failed at some point during the installation. As I looked at the site of Crucial, the update is not guaranteed to work on UEFI/GPT disks, so I'll have to wait until the right driver is started.

  However, I tried to fix by using the EasyBCD utility startup files, as a friend advised me. The problem does not appear since then (4 start-up), so I hope that this is resolved for now. It was probably caused by my fault during the installation/system tweaking. I'll definitely keep you posted on this.

  Thanks again,

• T440s uefi boot problem

  Hello

  I recently bought a thinkpad T440s (bios version 2.27), I was able to boot xubuntu in legacy mode, but did not start using the uefi.

  As I do this is to grab the last amd64 iso xubuntu desktop, run isohybrid on it, finally "burn" on a USB.

  To start using the uefi, I tried many settings, with or without 'secure mode', none worked, tried on all usb ports, no luck.

  When Googling this problem, I found a lot of posts on dual boot with windows (which is for example in uefi mode),
  but I'm not concerned about dual-boot ubuntu will be my single operating system.

  I know on uefi help pages, but I find it hard to understand what is relevant or not in my case.
  I wonder if someone with close hardware, managed to install xubuntu (or another version) using the uefi.

  This post somebody would tell me how to proceed?

  Thanks in advance for your attention.

  Best account.

  Hello

  You have just taught me something about the iso images :-)

  I was finally able to start using the uefi, specifically, he started with the handling

  You told me (make a fat32 partition, copy the contents of the iso image on this score unique flash drive)

  but xubuntu is stuck the GUI front.

  I retried in raw by copying the iso image on the flash drive (dd if = of =....) without any other manipulations

  and it worked.

  Thanks for your help

• After the passage of the UEFI boot problem boot in legacy (V5 - 471 g ACER WINDOWS 8)

  Hello! I just change the boot settings in the BIOS to UEFI for Legacy (Windows 8). After passing them, I turn on my laptop and I see "Operating system not found" and "Media test failure, check cable of...» "Moreover, I use an Acer V5 - 471 G Windows 8. Please help me! PS My W8 is pre-installed.

  That's what I did...

  the same thing as you...

  to solve this kind of mess...

  First, you must download from the acer site, the last driver BIOS for your laptop.

  (use another laptop)

  but you need to install a single... but don't worry, it will ask you if the file you are trying to install is not necessary... I used version 1.22... (it depends on the version of the bios, the starting version number must be the same., mine is 1. xxx 1.22, I was invited that installing it is not fair, she says that it is incompatible)

  then, once you have downloaded, unzip it...

  Make sure you have it on a USB (usb)

  Second, since you have the Disc... use it...

  http://www.SevenForums.com/tutorials/139810-SFC-SC

  This shows how to go to the command prompt by using repair disk (this can be win7 is virtually the same, only gui is different)

  go to repair your computer option where you will find many options...

  Choose the option to open a command prompt.

  as your in drive X: that is the container for the discount, go to the current folder of the file...

  X: > F: (if F is the letter of the usb key, then F, if not, then use the corresponding to the USB drive letter)
  ... go to the bios folder
  F: > cd BIOS_Acer_1.22_A_A/BIOS_Acer_1.22_Windows/Windows

  then run the Update.bat

  (must be that your battery must be greater than 30 %..)

  If so, simply run the Update.bat

  F:/BIOS_Acer_1.22_A_A/BIOS_Acer_1.22_Windows/Windows > Update.bat

  just wait and voila... it's fixed

  mine is aspire v5 471g

  just tried the boot legacy... and f2 was (as expected... does not work)

  I just did what I said here and it worked again, bios has been returned to factory settings and I just sit here having a smiling face...

  Thus, a very big reminder...

  What happened, never turn your computer off by updating of the bios... just to be sure of something stupid happens

  If this does not work... try again the 2.17 sir...

  Unzip the exe file it y...

  After that...

  Locate the update.bat and then run...

• ACER ASPIRE E5-511-ADD DEVICE USING THE UEFI BOOT.

  Hello. I bought a laptop Acer Aspire with Linux preinstalled E5-511. I want to install windows 8.1.

  I created with Rufus TPG bootable USB flash with win8.1 image. UEFI mode the laptop does not recognize the USB, I have turned off secure boot, put the USB - HDD on the top of the boot priority but in vain.

  In legacy BIOS mode, I can boot and install windows, but the touchpad mouse does not work, only the USB mouse functions.

  How can I add UEFI boot USB flash?

  Thank you in advance.

  You did right, but sometimes the USB interfaces are not recognized by the system, I had some problems with a pair of USB pen which has not worked as a boot device, but another one worked smoothly.

  don't forget to have your HDD or USB pen in FAT32.

• USB boot with UEFI charger problem

  Hi peepz I have a desktop HP 110 009el and I am trying to boot from USB on the UEFI boot loader, checked the bios and installs on top saves USB the changesand hit F9 to restar PC.

  the only options I see to restart on UEFI boot its only are the network bootloader... no USB or HDD doesn't appear...

  any ideas how boot USB charger UEFI?

  just to let is know I did installed USB no UEFI under Linux and tryied to install win7...

  the two worked great but wasn't UEFI.

  Thanks in ADVANCE!

  Hello

  Power off with the active UEFI USB device inserted into the PC. Now, turn on the PC and press ESC then press F9. The USB device should now be indicated by EFI.

  Most active UEFI PCs I've used require UEFI enabled devices to be connected to the current time in order to be recognized.

• Acer Aspire 5742 G died. I think the BIOS is damaged because all I get is a blank screen.

  I was a heavy task on my other laptop and I wanted more RAM, so I decided out of the 4gigs of my Aspire 5742 G only to find out that this is not not a 4 × 1 GB of RAM (instead a 2x2gb DDR3). All I've done is out of RAM, I saw that it was only 2gigs and put in (nothing else, I know my way around computers quite). Then I thought to share work on the network, only to find out that my Aspire 5742 G will not start. Nothing. Not eveb the Acer logo appears. Access to the hard drive led is always off (not a single blink). Terrified. I thought it would be to display, but like I said the HARD drive light flashes once again.

  So I jumped to Google. Discovered it probably a BIOS problem. So I downloaded the BIOS Acer will, comes to be welcomed with a ZIP file of gibberish. I have no idead how to use this ZIP to update my BIOS. The exe file is not good as the PC starts no and all other methods seem unlikely given the boot selection is not yet possible.

  Can someone please guide me to the right maybe average to refresh my BIOS?

  Thanks in advance,

  It may be almost impossible to diagnose a problem remotely, I hazard a guess and suggest that your problem has nothing to do with your BIOS.

  Given your description of your actions, I would recommend you check and double-check your RAM seats. Also, make sure there is no damage to the socket. There is also the probability that static was able to destroy the RAM. You may need to try known good RAM to exclude this possibility.

  It is not always possible to update a BIOS if there is a hardware problem.

  Of course, I can't risk a BIOS Setup until there is absolutely no doubt that a problem does not exist elsewhere. If an update attempt fails, you might find yourself worse. In short, make sure that your RAM and the seating is 100% before looking elsewhere. Your choice of courses.

• Aspire 5742 Bluetooth Stacker stopped working.

  Immediately after, boots mobile message "Bluetooth stack has stopped working". There are two options 1) search on the web for the solution and close the program 2) close the program. There is no need to select option 1. It provides no solution or information about the problem. I tried all of the solutions provided by Windows Help. I also deleted the "Suite Bluetooth Win 7 (64) and pilots." the same error occurs after relaoding after the software and drivers. I can't connect to any Bluetooth device without encountering the error. Is there a solution? If not, are there other available software that are compatible with the Atheros Wireless adapter included with the Aspire 5742?

  Thank you for your response.

  Since the last version of the driver has not fixed my problem, I reloaded the operating system, programs, and drivers. Now the bluetooth works properly.

• Aspire 5742 recovery disc question

  This is a long post.  I went through a lot of steps already.  I'm not an expert in technology, but I read directions well (most of the time), and my knowledge comes from working through the problems as they come.  I use a newer laptop to make different drives and disks.

  I have an Acer Aspire 5742 Windows 7 hp 08. I had a few deep-rooted malware and decided to do a system restore. The system restore worked and the first thing I did was last updated from windows. There were 192 updates and it took a few hours for them to download and install. After the restart, while it was down to the 5 latest updates to install, a message appeared on the screen, indicating that updates failed, and all of the updates would return. Eight hours later nothing had changed. The screen looked exactly the same. I don't know if I did the wrong thing, but I assumed that the restoration was in an infinite loop and made a decision to perform recovery with my Acer OEM drives.

  There is a system disk and the value of three with the Acer recovery disks. I don't know if all the recovery disks work exactly the same but in case they are not, I will include the information which has come to the screen. After the system disk is inserted and that windows support files, the options in this box Acer Recovery Management are-

  Restore OS - OS restore to default factory default status. All the data on the C: drive will be deleted. (It was the option that I tried to use)
  Restore the operating system and to keep the data of the user - only restore the operating system of your PC to the factory default. Your user account files will be transferred to C:\backup. This option does not remove the malware. (When I tried this: no user data were found on your computer)
  Fully restore computer to factory settings - restore your computer back to the factory default state. All data in the hidden partition and the system partition will be restored. Before restoring, please delete all data on the hard drive (when I tried this: Please delete all files from your hard drive before you start.) This function will not work if there is no file on the hard disk.)

  So by clicking on option 1, there's the box in the view of what is happening. The area becomes "restore the Destination."
  The hard drive name: ST500LM000 - 1EJ162 ATA device
  Partition label: Acer
  Size 8.0 GB partition
  Copy of disk files.
  Please insert the restore disc 1.
  Copy of disk files
  Insert disk 2.
  Copy of disk files
  Insert disk 3 (it is 80% complete)
  Copy of disk files.

  Shortly after that the disk turns on a message box appears saying "There are not enough disk space for the temporary files needed for this operation"

  Press Ok. Wait a minute please. Acer boot screen then back "BOOTMGR is missing. Press Ctrl + Alt + Delete.
  Pressing C + A + earrings back to the boot screen Acer and return to "BOOTMGR, etc.".
   
  The original crapped out drive and I replaced it with a hybrid 500 GB drive.  I have partitioned the hard drive for the upgrade of windows 8, which was offered when I bought the laptop.  I rarely used it, and it remained a 20 GB partition.  Think that the partition might be the problem I downloaded the portable computer Wizard mini partition my new tool and copied the files to a CD, a DVD and a flash drive.  All contained errors. Failure of the Conference on disarmament.  I tried another, he sounded like he was going to start and then returned to the screen BOOTMGR.  I pulled out a blank dvd, copied the file .iso from the score to it. The message on the screen: drive hard virtual cannot be mounted from image files or from removable media that is not formatted with the NTFS file.

  I dug around and eventually find my flash drives. The flash player has a default FAT32 and I changed to NTFS (based on the above message) and formatted. I copied the file to the partition.  The message on the screen: a BONE was not found. Try disconnecting all drives that do not contain a BONE.  I made in all attempts above that I changed the boot order in the bios.

  I tried another flash drive and kept the default FAT32.  It would sound like he was trying to start then:
  PX - E61 Media test failure. Check the cable of
  Output of MOF broadcom PXE

  What I am doing wrong?  What can I do to correct this player so that it be cleaned?

  I forgot that I had an external enclosure for a hard drive, so I took out the hard drive for Acer and it subservient to my new laptop. I bought it when the original Acer hard drive became corrupt to try to look at the files. Here I am trying to understand the hard and a less complicated solution (for me) was at hand.  Of course, he had 4 partitions with only 8 GB for the Acer.  Don't know how it happened.  I am planning to wipe the disk completely and using the disks from Acer to start all over again.

  Please accept my sincere thanks for taking the time to help me.  I learn something new every time I have to correct a problem and without the help of message boards I would be screwed.

• Acer aspire 5742 does not start

  Hi all hope you can help - I have an acer aspire 5742 running windows 7. the problem is that it doesn't start not until after bios acer launched toward the top of page and just continuously loop around.

  can you please help

  Hi - I've worked with thanks to you all, I'll wish to explain how to fix at the base.

  1 - Download partition manager free 2014. http://www.Paragon-Software.com/home/pm-express/

  2. run the partition manager and select go delet.

  3 - Select the partition that has 100 MB space and delete

  4. then select the larger partition and delete.

  5 - turn off the power to the laptop

  6 - Turn on the laptop

  7. when the acer page appears, press ALT + F10 ONLY once.

• Satellite L50D - Boot problems after replacing the hard drive

  I just upgraded my hard drive of the pathetic crod 5400 they provide to a SSHD@7200rpm, but now have a major issue.

  I initially image the operating system from the old hard drive to the new drive and have had chronic start-up problems (1-3-4 attempts to start to succeed if it fails at any time (often to the Toshiba start screen)).

  I reinstalled from a drive under Win 8.1 plain own ENT (trying to avoid the bloatware) and it is exactly the same number and is what I used to format the laptop very well with previously and had previously worked.

  I tried reformatting and reinstalling (by removing all partitions on each attempt) to the CSM, unsafe UEFI and UEFI secure. MCS is a straight line never works not proceed and both UEFI methods have the same exact result.

  I tried with original restore disks and it seems to work (not had time to fully test) but I don't want the bloatware and it shouldn't be serious since, if I were a customer who forgot to make restore disks (too often) and just have to have a failed hard drive or replaced sacrificed the laptop would be now a door stop.

  This seems as bad as Apple to lock people in.

  So I would appreciate ideas of people to please, I don't know if there is a program that is supposed to take place on a new drive as PS3 etc (I doubt it), but that leads me into the wall, and will be the last time that I consider Toshiba as anything other than a joke, if there is no solution.

  I had to replace the hard disks many times in my previous Toshiba laptops and were devoid of this crod, it has something to do with UEFI which seems more a nuisance than a help right now.

  TIA.

  Hello

  In my opinion, you should first check if the startup problem is related to the new installed HARD drive or new installed system.
  You said that the laptop fails to start up often to the Toshiba start screen.

  The splash screen appears during the POST (power on self-test) procedure. During this test, the material will be checked.
  I m wondering if the hybrid SSD/HDD isn't recognised by the BIOS during this particular step.

  From my point of few, this could be the reason why the system cannot be started.

  Another important note:
  The 8.1 win requires enable start secure as well as the UEFI boot mode.
  Therefore, you must enable both options in the BIOS.

  Last but not least check if you are using the latest BIOS version as latest firmware for the hybrid SSD/HDD

• Satellite Pro C50: Installation of Win 7 using the UEFI boot mode

  I want to install Windows 7 Pro 64 bit on Sat Pro C50 (downgrade if you like - comes with 8 win), but I want UEFI boot, with GPT partitioning.
  I'm happy wipe existing partitions if that solved the problem.

  I have disabled _have_ Secure Boot.
  Win 8 install DVD boot works;
  CSM boot and boot from Win 7 DVD works - but this is not what I want.
  Definition of return to the UEFI boot and install Win7 boot media - hangs on "Starting Windows" screen
  Media _is_ good, works well on the PC manufacturers.

  I'm not convinced that it is a problem of Microsoft.

  Hello

  On Toshiba laptops, where the UEFI BIOS is available, it of necessary to disable secure boot and change the boot to the CSM mode in order to boot from external sources and install systems other than Win 8 or 8.1 Win

  Of the workarounds in the internet described the installation of Windows 7 in UEFI mode but I doubt that this will be possible on Toshiba laptops because the BIOS is different and modified for each series of laptop.

• Acer aspire switch 10 no boot device

  Hello, I am working on an Acer Aspire Switch 10 2 in 1 (there so no usb port and no cd drive) when I turn it on it flashes Acer logo for a second and then jump to "No boot device" with an image of a hard drive and a magnifying glass. This was not the case before. I could get for the recovery and trying, but it did not work. Now it seems that when I go in the settings of UEFI, boot order options have nothing other than IPV4 and peripheral USB for possible boot options.

  On information in the BIOS, you can find any reference to the members of the SSD?

  If this isn't the case, it is probably a hardware failure.

• ACER Aspire 5742 i5 with 16 GB of RAM?

  Hello

  I have an Acer Aspire 5742 i5 model, now with 8 GB of RAM.

  I tried to install the two 8 GB DDR3 modules, but the machine will not work. It will boot, but crashes on Ubuntu when I connect.

  I tried memtest86 and it crashes almost immediately.

  I've already updated the BIOS with the latest version I could find (1.30), but not luck...

  When I go into the BIOS, he notices the extra memory, although the screen shows only 4 characters (6384 instead of 16384).

  I tried just one 8 GB modules, one of them with another 4 GB (12 GB total) etc. All attempts have resulted in the same way: Boot, but the accident.

  Officially, I know it supports only 8GB, but the other laptop where I write is also an i5 that officially goes up to only 8 GB, but is now happy with the same memory modules...

  So, I was wondering... is - this really impossible to have 16 GB on this model? Or is there a workaround? I searched (Google takes me...) and I couldn't find a solution...

  At least, I would like to know the reason why it does not work... BIOS?, Chipset? CPU?

  Thanks in advance.

  Hello domusonline,

  You said "I have an Acer Aspire 5742 i5 model". For example, the processor Intel Core i5 - 480 M processor---> max memory size: 8 GB.

  Check your model of processor on the Intel site.
