• (Bootcamp) Windows 10 becomes black and restarts on bootcamp

  After installation of Windows 10 on bootcamp and navigation just normally as any other people would, after 10-15 minutes my screen suddenly goes black and restarts...

  While it has been restarted, blue "windows" sautéed as usual and points to bicycle in a circle turns on for a few seconds and then it crashes, restarts again...

  At this point I keep restarting and then it comes to auto repair, that I then used Safe Mode to get in which worked but I could not do much with it because she persisted again after the reboot.

  • The files are on a 'Macintosh HD' partition in a 1 TB HARD drive
  • I have Windows Bootcamp installed on a "SOLID" NTFS partition in the same 500GB SSD
  • and another NTFS partition for Windows files "LIQUID" in the same 1 TB HARD drive
  • I also have a new partition (which lead to my problem) "ScratchDisk' in the same 500GB SSD

  Also very "SOLID" and "LIQUID" NTFS partitions are currently read-only that is ' owners: disabled "in disk utility after creating a new partition"ScratchDisk"for Photoshop in the same 500GB SSD and SOLID will not show up to start up after pressing the button 'Option '.

• El capitan update taking 30 mins excess and starting to install. is this just an i5 processor?

  I tried to install the last update at el capitan and after the reboot, the screen goes white with just the cursor indicating for 30mins + and waited so he can continue starting.  I waited 17mins first, then tried to turn off and then turn it back on.  He did the same thing again. My machine is a model (October 2015) 27 "recent iMac running a processor i5 and 8 GB Ram

  Don't know if it will make a difference, but you can download the update Combo here, Download OS X El Capitan 10.11.6 Combo Update and then install. Once the installation program will restart you will get a black screen for a short time, then the Mac should start to a gray screen with the Apple logo and a progress bar, which should show an approximate count.

  Make sure that your Mac has enough free space, 10GBs or more must be fine and also use disk utility

  to perform a check on the disk before and after everything settles. If she needs repaired, you start in your recovery Partition and disk utility.

• ProBook 4330 s: what disk partition I can't delete without future problems

  Hello

  I need create simple disk partition, but I can't because there are four primary disk partitions - system, HP, HP Recovery and C tools. My application is which of these can I delete and keep the current functionality of victory. I don't know if HP tools is not necessary for the recovery disk and I find that the system disk are important information which are using System.

  Can I save disk tools on CD and computer HP will still work? Or is the best backup idea recovery disk? Information on the internet are different. Single site Web HP tools remove the other says delete system. But there are other sizes of this disc I have. My HP tools partition have 2.4 GB and 300 MB system.

  HP_Tools partition has the Diagnostics

  Recovery partition has the recovery that are accessible with a key F11 to restart Manager.

  System partition is required by the operating system

  C partition contains the operating system and is also where you store everything and run programs.

  If you have created a recovery from USB or disk set with the HP retrieve creator of media already, then you can safely remove the recovery partition. Be aware that you will lose the built in functionality to have the Recovery Manager. F11 won't do anything.

• El Capitan utility disk first aid fails - unable to unmount the volume for repair

  Question: Given the following error with Disk Utility first aid and success with diskutil check volume, I should consider my drive damaged or volume?

  After a crash of the system on my Mac mini (end 2012) running that OS X El Capitan 10.11.3 has experienced a kernel panic induced by the adapter USB Wi - Fi, I dutifully ran first aid utility disk on each volume on the disk, in order to ensure the integrity of system files.

  Additional information: I didn't have any problems with this disk volume. I use it only as a Time Machine backup destination. It is an encrypted volume OS X Extended (respect for case-sensitive). My concern involves only disk utility complaint that its "first aid process has failed."

  After reading the complaints in other forums that utility disk on El Capitan has been "dumbed down" and can not perform many of the functions that the utility of the same name used to be able to perform in previous versions of Mac OS (complaints, I can't confirm because I'm relatively new to MacOS - although extremely in computing with Windows, UNIX and Linux) (, so I didn't get to use disk utility a lot, before El Capitan), I decided to do the same "check the volume" that I knew first aid was trying to perform with the diskutil command-line app.  Guess what? No error!:

  I think you might be able to do a repair of first aid, after you have disassembled the drive first:

  1. Run OS X by an external device (ex: USB mode, or external hard drive or disk target from another Mac)
  2. Launch the Terminal and run the following command umount f /Volumes/ (ex: umount f/Volumes/Macintosh\ HD)
  3. Then run disk utility first aid.

  I had this problem on a Macbook Air, I tried to recreate the image to work, so I didn't need to get anything off the drive. I tried to format the drive and reinstall OS X. So I don't know if first aid work after disassembly, but it worked without a doubt after that I did the first two steps above and then deleted from the disk. Not sure if this will help, but worth a try, I guess.

• Update Windows stuck in a loop. Keeps trying to download page 3 of 3, but never does, then restarts and is trying to download. Can't seem to put an end to the loop.

  Update Windows stuck in a loop. Keeps trying to download page 3 of 3, but never does, then restarts and is trying to download. Can't stop the loop to try something else.

  The operating system is Windows Vista.

  I found this as a solution and to share it here, I still have questions, but thinking might help someone.

  Windows Vista and 7 update Reboot Loop Fix

  Symptom: You have a update that is causing Windows Vista or Windows 7, stuck in an infinite loop. The problem usually manifests as a "step 3 of 3:0 % complete...". "followed by a restart which starts at the exact same message, not allowing you to get on your account of connection or a desktop at all. It's a pain, and he doesn't stop, even in Mode without failure or advanced trying last good known Configuration in the start menu.

  Here is the short version for people who know how to get to tools to do this and if run System Restore from the installation DVD does not work: DELETE files

  \Windows\WinSxS\cleanup.XML AND (as applicable)
  

  \Windows\WinSxS\pending.XML and the infinite loop update will be set.

  There are two ways to get the files, you need to delete. The easiest is to start your installation of Windows and the button 'Install now' DVD, click on the link located at the bottom left that says 'Repair your computer' open a command prompt and type:

  del C:\Windows\WinSxS\cleanup.xml

  del C:\Windows\WinSxS\pending.xml

  The other way is to download a live Linux distribution such as the System of Tritech Service (which, unlike Vista or 7 DVD, can be booted from a USB flash drive for computers with no CD/DVD drive such as netbooks), open a command prompt, mount the file system and deleting the files. Assuming that your Windows installation is the first partition on the first hard disk, the following commands in rxvt or a console in the Tritech Service system should work:

  Mount.NTFS - 3 g/dev/sda1/mnt/sda1

  RM /mnt/sda1/Windows/*/cleanup.xml /mnt/sda1/Windows/*/pending.xml

  umount/mnt/sda1

  discount to zero f

  Anyway you do it, this solution will stop the engine update loop reboot and let you return to your computer. You may need to make some corrections, additional or manual updates if you have problems, but unless your login screen and/or the Office should be accessible! Is a very annoying problem and I noticed that Google is looking for things like "stage of vista 3 3 restart" usually only provides information about how to run the system on a Vista DVD restore. Unfortunately, if there is a problem with an update, sometimes the system restore does not work and fail with obscure errors, so this info is vital.

  Maybe it's your last chance to avoid giving to the top and reinstalling Windows, and we always like avoiding relocations!

• Windows keeps freezing, then running dskchk to restart and still then freezes Help!

  Last night I've used Skype and some other Web pages open as well when my computer suddenly froze and I had to reboot. When I did, he worked briefly, but froze again. On the second reboot, he said he had to check the drive for consistency. Everything went well and was able to use it again for a few minutes, but when you type in a document in word, I got the blue screen of death, which said BAD_POOL_HEADER. However, after restarting, I not had the BSOD again. It freezes just up during use, runs the check of the drive even again and again, but continues to freeze later. The arrow works, but absolutely nothing else. I can't even run the computer in safe mode.

  I also noticed it says "recovering orphaned files" and "error correction in the index $I30 in file 50705" throughout the dskchk. There was something to find 19 unindexed files as well. In addition, the last time that I have restarted, he said that Skype is a corrupted file. I uninstalled Skype but this does seem to doing nothing at all.

  Looks like there's a LOT of different things going on here and I'm not that great with computers so I don't know what to do. All I can find are forums online and none were particularly useful. I live in the South of Senegal, so I can't exactly go to a workshop to repair either...
