Re: Trashed a boot partition?? Dynamic Disk - wrong drive letter

Try the MAP command in the Recovery Console, to reorganize the drive

and edit the boot.ini file in C:\     Also once logged on you can change
back the drive letters in HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices but be
advised that changing the system drive letter can render the system
unbootable, it can be changed back if it was changed but it's not without
risk.

To make the Boot Disk copy the necessary files to a formatted diskette from
another computer with Windows XP... files are :  Boot.ini, NTLDR and
NTDETECT.com... Or download the files from
http://www.bootdisk.com/bootdisk.htm  or directly from

Sadly it won't work, Jaun. Dynamic Disks are only useable in the system that converted them. See my reply to the OP.

I have a friend who got a little over his head in trying to repair his
PC.

He had a PC that was virus-infected, and figured the best way to scan
the drive was to take it out, put it in another PC as secondary drive
and scan it from that PC.

So he connected it to another PC - but this was a 160 GB drive and
Windows XP only saw it as 137 GB.  I think the BIOS in that 2nd PC is
outdated.  He thought, "HMM whats this dynamic/basic disk stuff" and in
Disk Manager he converted it to a dynamic disk.  Of course this did not
fix the 137 GB limit problem, and when he put the drive back into his
original PC, it would not boot.

I said I'd help him out, and I booted to the Recovery Console from the
XP disk, and ran a chkdsk which repaired some problems.  BUT the drive
is now coming us as D: instead of C: - and so, Windows fails pretty
early in the boot process, with a "cannot find autochk.exe" and then
blue screen.  Also, XP CD will not allow a repair installation.

Is there a simple way in the Recovery Console to set the drive letter
back to C:?  If Windows still wont boot, at least the repair
installation should get him back up & running.

Any help would be appreciated
