Hi henk,
First thing that comes to mind is what is the make/model of the computer with the failed WinX upgrade? desktop or laptop?
Next, did you or your friend remember to run the WX Upgrade Assistant prior to clicking the upgrade button?
Haven't seen this exact error code--did you try to google it? (not that that would help-LOL!).
There are several things that I would try:
1. Test the hard drive with
SEATOOLS, and see if the hard drive is failing or faulty. If your friend's computer is 5 yrs. old or older that's highly likely. If you run
BOTH short and long tests, and either returns an error, that hard drive is faulty and must be replaced.
2. Once you determine if the hard drive is ok, and rule out hardware issues, it could be driver corruption, or windows file corruption or something software related and you can then troubleshoot software--Windows installation--from there.
3. On the Comodo; I haven't had many Customers run this, and it's not on my list of approved AV programs, so, yes, I would definitely uninstall it--but,
make sure you or your friend has a recent backup of all his Personal Data to external media which includes all his Documents, Photos, Music, Videos, E-mails, checkbook, etc. PRIOR to start ripping out various programs including AV's, antispyware, firewall, etc. If your friend doesn't know if he has a recent backup or not, or he gives you a blank stare and says
"what's a backup?"; it's time to do one!! Also, lots of AV's don't remove properly so make sure to remove in
SAFE MODE if possible.
4. FYI, I think your wording is confused; the C: drive may hold the Recovery or Restore partition, but not the other way around. If he has a desktop, he may have a 2nd or 3rd internal or external hard drive; and sometimes those partitions can be installed on another physical hard drive (such as Drive1, Drive2; not Drive0--C: drive). Win10 won't mess with most factory partitions from what I've seen. On my Sony laptop, I have only 1 internal hdd, and it had Win7 on it previously with a factory Recovery partition installed for Vista. Win10 upgrade ignored that partition, and it's still there. The rollback program Microsoft has given everyone must be applied within 30 days of the upgrade. I have yet to test this. Several people have tried it with very unpredictable results. This is Microsoft's usual panacea--if you don't like Win10 or you can't figure out how to make it work or how to use it, just rollback to your previous version of Windows! LOL. That's incredibly obtuse IMO.
5. You didn't say which version of Windows your friend was attempting to upgrade from (Win7/8/8.1); it would certainly be helpful to know this (along with the make/model of the computer as i mention above). Was it done via Internet or a Clean Install method (DVD or USB)? I would suggest you attempt to rollback his system to whatever Windows came on that machine originally--that you can get to using the built-in Recovery Partition on the hard drive, say Win7; then download and run the Win10 Upgrade Assistant. Remove all non-WX compliant drivers and programs per instructions from the Upgrade Assistant. Then ensure you've unplugged
ALL USB or Firewire devices plugged into your friend's computer, and continue the Upgrade if you go the online method.
If you Clean Install, make sure to do this too; as it could easily be one of your friend's peripherals like a printer/scanner/camera hanging up the WX upgrade!! Especially if it's older than 5 yrs. and the drivers are too old to work with WX. 6. You can also try a Windows repair at this point. Open up an Admin Command Prompt, and run
CHKDISK /F on the C: boot drive. If it can't run to completion, your Windows is hosed and needs to be reinstalled.
7. If
CHKDSK works; go back and open up another Admin Command Prompt and run:
SFC/SCANNOW; you may be familiar with this one; it can take several hours especially if your friend's hard drive is larger than 750GB in size; it has to complete 5 stages including several reboots. If it runs to completion, it will fix any corrupted or missing Windows system files. I would do this on the factory installed version of Windows (Win7/8/8.1) prior to re-attempting the upgrade. After running Windows repairs in
#6 & here in
#7; see if the upgrade to WinX works. If it doesn't you'll have to perform the other upgrade steps; and a Windows reset most likely.
Best of luck,
<<<BIGBEARJEDI>>> Just remember my motto;
"Win10 upgrades won't fix pre-existing problems on any computer; if the computer wasn't running healthy on the earlier version of Windows; the upgrade won't fix everything!".
