The Boot-Up sequence issue?

Similar Questions

• Read the table for the next value (sequence issue)

  Is there a function in line with my_seq_no.nextval that can read a value from the previous field and get the next number in the sequence? I know how to create a sequence, but I thought that there is something as a function of getnextval.
  
  Thank you.

  Preston,

  The problem is that there is no such thing as a previous value in Oracle.
  You must specify a way (like number maximum.. etc..) to get the expected value.

  Sometimes, you can see the code as...

  insert into emp values
  (select max(empid) + 1 from emp) new_emp_id,
  ''XYZ' ename,
  .......
  ....
  ...
  from dual;
  

  As seen... the code above takes the maximum value of the emp table and gives you the identificateursuivant emp.

  The problem here is that all currently connected users will get the same value for the new empid, until a person inserts a record, then... all others would be unique constraint errors (if you have constraints on the right in place).

  Using sequences is the right way to ensure that all concurrent users get their own unique values for the new values.

  As for the getnextval, they could always get to a function which selects to the max (column-name) + 1 and returns it... but it has the same problems as the insert... Select above... So I would rather not provide code for such a thing... I would do more damage than help it. Please use a sequence for your case.

• u2913wm stuck in 'power save mode' in the boot sequence

  Hello

  Just got my new u2913wm today.

  I encountered the following problem: at startup, the screen briefly displays "entering power save mode" and stays black until the Windows7 interface was loaded. As a result, I can no longer access the bios of my computer.

  My computer is an Inspiron from Dell 530 s with Windows7. There is no this problem when connected to my screen LCD older (other brand).

  Is there a solution?

  Thanks in advance

  Hi ALI,

  I am pleased to say that the problem has been resolved with my new video card: AMD Radeon HD 6450. With this card connected via DVI, the screen remains standing throughout the boot sequence.

  It seems that there is a compatibility issue with some video cards.

• How to change the boot on Satellite 5100 sequence?

  Hello, I don't seem to be able to change the boot sequence for my 5100 satellite. I tried pressing C, F2, F12 and any other allmost touches possible.

  I also tried pressing ESC to access the bios. When I Press esc, I wonder the password that I created long time ago. When I entered the password all that shows on the screen is "Press F1 to enter normal setup" or something like that, if I have not seen to be able to enter the bios.

  Does anyone know a solution to my problem? I need to change the boot sequence

  Hi Lethin,

  I think your laptop is "Legacy free" which means that you have no way to directly access the BIOS.

  Any updates or changes to your BIOS must be made of in Windows.

• Compaq presario cq61: change the boot sequence

  I have 10 Windows upgrade on my compaq Presario cq61 free. I want to do a clean install of Windows 10. I downloaded the tool of Microsoft Media, made a key USB and DVD containing the clean install. I am told that the use of the flash player, I have to change the boot sequence in the bios. I tried everything from ESC, all numbers F and LED to try to enter the bios and all have failed. Told me that all I had to do with the DVD was just put it in and start the computer and the laptop would boot from the DVD and I could make my own installation from there. Which also failed. The only thing I have not tried is downgrade to Windows 7, affecting Windows 7 back to factory settings, then reinstall the free update of Windows 10. I would not have to go through all if I mostly because I bought the laptop from a friend and it was installed at the factory of Windows 7 and I don't got no disc software to the computer so I don't want to screw up and drop windows 7 without the appropriate software reinstall to match the product key.

  Any help to enter in the bios or advice that could help me reach my goal would be greatly appreciated.

  Hello

  Here are some other suggestions.

  1. start the machine in Windows 10.

  Open settings and select System.  Select food and sleep, and then click additional power settings - in the next window, click on "Choose what the power button" in the left pane.

  In the next window, click on "Change settings that are currently unavailable" (close), then Remove the check mark from the box against 'Turn on a quick start (recommended) '.  Click on the button Save the settings, and then close any open windows and stop the laptop by right clicking on the icon from the Start Menu, then select prompt (Admin) and click 'Yes' to the uac prompt.

  Type (or copy and paste) the following command (including spaces) and click Enter.

  Shutdown /s /t 0

  Tap on the ESC key as soon as you turn it on and see if it will now access the Start Menu.

  2 try to connect a keyboard external usb and see if this will allow you to access the Start Menu.

• Satellite problem BIOS L750 - cannot change the boot sequence

  Hello reader/answering my questions.
  I am having trouble with my 750 ODN bios. This bios is an official update (3.6) from the center of support, and almost everything has been fine since (the plot thickens!). I decided one day I want to dual boot with linux, in particular Fedora (this is unrelated to this though).

  But, when I burned the disc and tried to direct (too test) boot the boot order has been on hard drive, first of all, I found! I rebooted and pressed f12 - did not work.
  I tried to delete and escape - neither worked. Then, I tried all the f keys - none of them worked.
  Whenever he took me to the Windows Start menu, and I explored it and I could not find anything.

  It is also important to mention that I'm under Win 7 SP1.
  I tried both PLoP and osloader (too boot from the dvd) - neither worked.
  I also do not remember what the button to start the bios was originally - Oops!

  Also toshiba with instructions logo never appears.
  I would really just change the order of boot however, the rest of the bios I don't need access too much right now.

  A separate issue is that Windows randomly decides he wants to check my hard drive, which takes forever, and he won't until he arrives to check it out. I think it may need medical help.

  But, no help, a qualified doctor or not, would be greatly appreciated.

  Thanks in advance

  Hello

  > I also don't remember what the button to start the bios was originally - Oops!

  Pressing F2 by turning on the device could help you access the BIOS.
  But you do not need to change the boot order in the BIOS. You can do it by pressing F12. This should be done immediately after you have turned on the laptop.
  Then the start menu appears and you can choose the right boot device.

  Does it function?

• (Redirected) DELL POWER EDGE Server 720 R - no boot messages sequence appearing while the server starts

  Hello

  I have a dell 720 R service class machine. In general, the system should display the boot messages during boot sequence. As the logo DELL followed hard details of memory, disk and network hardware card / other details etc. Is it not?

  But my machine shows no such messages to the screen during startup. There remain a Virgin until he enters the desktop screen. What could be the cause and the solution to this problem? For this reason, I am not able to choose boot options, or anything during startup. In the hope of a solution to this case.

• Change the boot sequence

  Hi all

  I was wondering if anyone has a guide step by step (with pictures) on how to change the boot sequence (I'm not interested by a particular brand of PC or a particular Windows).

  Thanks in advance :)

  Adam

  There are a few different ways to access a page of options boot menu at startup

  Bios legacy would use the delete key

  UEFI BIOS would use F8

  Each you could enter the bios and select the or change the first device to boot cd / dvd drive is usually first "inline"

  Some uefi bios and or install uefi, you may enter win - 10 or 8 - 8.1 and turn off the quick start first in = power options change what the button of power before you could even get into the bios because of the characteristics of secure of the two of them start.

• Cannot change the boot sequence in the bios

  Hello world!

  I use vmware fusion 3.1.1 (282344) (in fact has happened since I started from 3.0). A home edition of Windows XP is installed in the bootcamp partition and is used as the guest operating system. When I start Windows XP, it always first try to boot from the network, which takes about 1 min (this can be ignored by hitting the ESC key however). Even if I enter the bios settings, the starting sequences is not editable, where "everything on this menu is not editable in user mode. If all items require changes, consult your supervisor system"is written. However, no password supervisor and of course, I'm not using the 'user '. Does anyone have any ideas on this?

  PS: a full Linux guest OS (installed in fusion and is wrapped up as a file) has no problem to change the boot sequence.

  Best regards

  All items of this menu cannot be changed in user mode. If all items require changes, consult your supervisor system

  Weird, I never heard of this message before. You get this when you start merging, not in native mode? I would have asked if someone had made changes to the BIOS settings until you got to the virtual machine, except that you said it's Boot Camp, so I think it's less likely.

  You can try to change the boot order in the Virtual Machine > settings > advanced > boot device.

• OptiPlex 755 denies access to the boot sequence menu.

  Found a weird problem on an Optiplex 755 Desktop Tower System.

  I can change other values available on the system, but cannot get into the boot sequence menu.  The BIOS that was on the system was A17.

  Updated the A20. No change.

  Oh. It wasn't later. Upgrade to A21.  No change.

  Downgraded to A12.  No change. Faced A21. No change.

  Demoted in A10. No change. Faced A21. No change.

  Decommissioned at A01. No change. A21 encountered no change.

  If there is a password on the system when I tried to access the boot sequence menu it reminded me that I needed to type first. After correctly entering this value, the guest went away, but I still couldn't get into the boot sequence.

  I removed the battery cmos for 20 minutes while the system has been disabled, it put, started. No change.

  I replaced the battery cmos with that of another system.  No change.

  Tried another keyboard. No change.

  The jumper to reset the cmos.  No change.  A run the utilities on board.  No error could be found.

  If I hold the Enter key while on the boot sequence menu I can see the screen initial start-up and glimmers of it will not advance to the next screen.

  Unplugged the system and pressed the button for 30 to 60 seconds. No change.

  I think it's ripe for a replacement under warranty.

  I know that this response comes a little late, but for someone else has this problem...

  IT CAN BE FIXED!

  This problem seems to arise after a BIOS updated completely flashing properly. That leaves the user unable to change the boot device priority in BIOS, causing therefore the machine complaining that there, there is "No Boot Device available"

  Making level and the average standard BIOS downgrade do not seem to work; However with some switches it can be done.

  First of all, you need the BIOS first release, A01 (O755-A01. (EXE), currently available from http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=R164252

  Second, you will need also the latest version of the BIOS, A22 (O755-A22. (EXE), currently available from http://www.dell.com/support/home/us/en/04/Drivers/DriversDetails?driverId=2DWTY

  Lastly, you need a USB stick or hard drive which is able to boot the machine in DOS. It is recommended to use the free 'Rufus' tool to create a bootable FreeDOS. Rufus is currently available at https://rufus.akeo.ie/

  In addition, you may need to install jumper on the motherboard service mode; This repair was completed successfully with him helped, although it * might * work without it installed, although this has not been tested.

  First create a FreeDOS using Rufus bootable USB device. When complete, copy the two BIOS A01 (O755-A01. (EXE) and BIOS A22 (O755-A22. (EXE) to the root of the memory stick.

  Insert the memory stick into the computer, and then press F12 for BIOS. Boot from the USB key. Once at the DOS prompt, type:

  O755-A01 - wipeall - wipeclean

  Press on enter and follow the prompts on the screen. After the BIOS has been flashed, the computer must restart. Go into the BIOS and check the options under system boot sequence. The boot sequence should now not only display the name of your hard drive, but will be variable, allowing your computer to start normally. Set up your BIOS Setup to your liking (including date and time setting) and save it then & leave. After the reboot, press F12 again and start once more the USB device.

  Flash the BIOS A22 the standard way by typing O755-A22 pressing on enter. Follow the prompts on the screen. Once the BIOS has been flashed, check the settings of the BIOS again to make sure that the Boot Device menu is always available.

  Once finished, be sure to remove the rider of mode of service (if installed).

  FAQ

  Why it works?

  
  From what I can tell, the previous BIOS flashing tool includes switches that later versions are not. -wipeclean - and wipeall are an integral part of this fix works as they completely erasing all the BIOS settings that are not usually deleted when the BIOS is updated. For some reason, Dell has removed these BIOS update tools options later.

  In addition, the previous BIOS flashing tool actually flashes the BIOS itself DOS rather than rely on the BIOS RAM loading and then Flash with routines in the BIOS of the current system. I have no idea if that makes a difference in the process, but I imagine that it allows more options to pass to the routine of flashing.

  Sorry for the long post, but I hope this helps someone! Having recently put his hands on a couple of these machines and having the same problem, it's incredibly frustrating.

• How to change the boot sequence?

  How can I change the sequenze boot, if it is not possible to open the boot with 'F12 menu '?

  I m wondering why you can't access the start menu?
  What laptop and how Windows system you have?

  Usually, you can change the startup mode in the BIOS settings. To access the BIOS you have to press the F2 key
  But you can also press a particular button while you turn on/off the device to boot from a single module.

  For example:
  C button-> CD/DVD drive
  Key U-> USB FDD
  N key-> internal LAN

• Unable to access the boot sequence in the BIOS

  I press ESC at startup, then F9. I can use the arrow keys to switch between 'the operating system startup Manager' and 'file. EFI Boot. But when I select "OS boot manager" and press on enter as the instructions on the screen, the date of the BIOS and Windows is loaded. How can I change the boot order?

  Hello

  The following assumes that you are trying to boot from an optical disc or flash drive.

  Tap the escape key when you rewind to enter the Boot Menu.

  Select the option in the Bios ( f10 )

  Select the 'System Configuration' tab, and then expand "Startup Options".

  Disable startup secure and enable legacy devices.

  Press f10, select Yes and press ENTER to save these settings.

  Note: When the machine restarts, you will be asked probably enter a number of 4-digit on the display to confirm the change of setting.

  Insert the bootable media.  Restart the computer and press once further to the esc to launch the Start Menu.  Select the Startup Manager ( f9 ), and I hope that the device you are trying to boot from will now be an option.

  Kind regards

• Cannot change the boot sequence

  Hello

  I'm trying to change my boot order, so that I can boot from a DVD on my laptop Pavilion (E8A72UA #ABA).  I pressed ESC to get the boot menu.  The menu says:

  F1 system information

  F2 System Diagnostics

  F9 boot device Options

  F10 BIOS Setup

  F11 recovery system

  ENTER - continue starting

  I tried pressing just F9 and Fn + F9 to get Boot Options and no job.  When I press Fn + F1 I can go to the screen that displays system information.  However, F2 and F9, F10 and F11 do nothing.  When I press Enter, it boots into Windows.

  I am doing something wrong or there at - it something wrong with the laptop?  The function keys work fine when I start in Windows, so I don't know that the function keys are not violated.

  Thanks in advance.

  Hello

  Once the unit is on keep tapping F10 key it will take in the settings menu of the BIOS.

  Then selected System Configuration then start Option, then boot order.

  Then change the setting you want to do. Press F10 to save the changes and exit the screen.
