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

Try the MAP command in the Recovery Console, to reorganize the drive
letters.. If that doesn't work use the FIXMBR command in the Recovery
Console.... or make a Boot disk to logon and make the necessary repairs to
the boot.ini file in the boot sector. Tools\Folder Options\View\Show hidden
files and folders and uncheck "Hide protected system files (recommended)"
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
http://1gighost.net/jerseyboy/xpquick.zip
