Re: Installed on USB, WinXP no longer boots
When you installed Ubuntu, Grub found Windows and now your boot order is screwed up because the grub info is on the flash drive. Insert you flash drive then when grub starts scroll down to Windows and see if it loads then. Most likely you will need to boot to a Windows install disk to correct your master boot record. After you boot from the CD choose Recovery console or ( r ). Open a command prompt and This web page explains the steps.
