Thanks for the tip mate. this is my boot.ini content [boot Loader] Timeout=30 Default=multi(0)disk(0)rdisk(1)partition(1)\WINDOWS [Operating Systems] C:\$WIN_NT$.~BT\BOOTSECT.DAT = "1st, text mode setup (Boot from flash again after finished)" multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="2nd, GUI mode setup, continue setup + 1st start of Windows" /fastdetect C:\ = "---> DEBUG options. Try if you have hal.dll error <---" multi(0)disk(0)rdisk(1)partition(2)\WINDOWS="Debug boot rDisk 1 partition 2" /fastdetect multi(0)disk(0)rdisk(1)partition(3)\WINDOWS="Debug boot rDisk 1 partition 3" /fastdetect multi(0)disk(0)rdisk(1)partition(4)\WINDOWS="Debug boot rDisk 1 partition 4" /fastdetect multi(0)disk(0)rdisk(2)partition(1)\WINDOWS="Debug boot rDisk 2 partition 1" /fastdetect multi(0)disk(0)rdisk(2)partition(2)\WINDOWS="Debug boot rDisk 2 partition 2" /fastdetect multi(0)disk(0)rdisk(2)partition(3)\WINDOWS="Debug boot rDisk 2 partition 3" /fastdetect multi(0)disk(0)rdisk(2)partition(4)\WINDOWS="Debug boot rDisk 2 partition 4" /fastdetect I tried all of the above and none was working.. and all of the Debug boot gives me this error "Windows could not start because of a computer disk hardware configuration problem. Could not read from the selected boot disk. Check boot path and disk hardware." When I installed the windows I had 2 USB attached to the PC.. And I installed my windows on 1 single partition, there isn't any other partitions In this case what should I do to get my windows working again? Cheers~
