I have a multi boot system; Win8, Win7, Vista, XP, Linux
While was working in XP I updated a very outdated Marvall Sata driver. I rebooted after as one should after a driver install, and XP would not boot. I moved to Win7 and saw in Windows Explorer that the XP drive was missing. I load Acronis Disk Director 11(ADD) and saw that the partition was still there but has no letter. I tried to use ADD to try and 'Change Letter' to the first available P:.
I rebooted as the program wanted and got back to win7. But the drive letter did not appear. I did this twice. I tried to view the partition with Windows 7 Disk Management program but it just froze when it got to the XP partition.
Any suggestions?
Thanks

Part of me is thinking don't ever update drivers unless it solves one of two things (or both!):
  • The old drivers have a serious bug
  • There's a huge security issue
In other words, if it isn't broke, don't fix it.

In any case, try running TestDisk to see if the partition is fine. And if it isn't, try restoring it.

Thanks for the reply.
I've been under the advice in this mag, and others that is it always best to have the latest drivers. For bug fixes, and increase in performance where possible. I never use 'beta' drivers, only "stable" versions. This may be an instance where a "stable" was in fact bad.
That aside.
TestDisk reports nothing wrong with the partition in question. Boot sector matches back up, it's partition is bootable. Yet it has no drive letter so the windows boot manager can't find the drive to boot to it.
This is very strange. Other ideas?

Does the boot manager even see Windows XP? If you can still access that part (like attempt to boot) then see if you can get into safe mode and roll the drivers back

Here is the pic of the boot

https://www.google.com/search?q=windows ... B541%3B371

I can't upload a real pic(?) forum will not let me.
My status line is 0xc0000000f
If I use an XP disk to fix the boot. It messes up all the rest. And make Linux useless. This from past experience.
I can't F8 the boot.

Very Very informative. Thanks, site bookmarked for future reference.
But my boot error ends in "f" not "e'"
XP boots differently than win 7/8. Win7/8 fixes do not work with XP. With a multi boot it adds some bit of complexity to the situation. What other thoughts might you have??
Your help is very appreciated!!

Well... if XP's bootloader is hosed then we have a problem. I mean I guess you could try to fix that, then run the fix for Windows 7, then throw in GRUB.
