I have IBM Thinkpad R50e with Windows XP and also Ubuntu. When I start XP it goes blue with the .. 0x00000007B (0xF99B4640) 0000 .... text. I tried to recover with XP cd but it wount reboot from the cd. Changing the BIOS startup/boot priorites doesnt help. The reason why I have XP and Ubuntu is because in past, similar thing happend. My computer turned off and I was unabel to start XP. But I needed enthernet so I installed Ubuntu. Any ideas of how I can recover my computer with XP would be helpful. Oliver.
