I had window 98 and xp on my computer, a week ago all disappeared. I want to install xp another time. There are C, D, E, F,G drives on the hard, totally 20gig. Some necessary documents have been copied on F. I downloaded XP setup disks and followed the instructions. For several times I saw blue screen with an error message coded with IRQL_NOT_LESS_OR_EQUAL, and something about the BIOS and changing its configuration, which I couldn’t understand. However I changed the disabled the Shadow and try it another time but didn’t work. Only one time all XP files copied but after restarting the message was: “Invalid partition table”, the same message when I start the computer without any boost disk. I tried to boot it with several boot floppy disks( DOS,XP). It starts but it can’t recognize even C drive! Only when it is booted from Win98 start-up floppy, it recognises the all drives as well as CD-drive. In this case when I want to install XP from CD it says: this program can’t run in DOS. I asked this question a week ago and received the suggestion for FADISK but : won’t all file on F be formatted? And will it fix the problem? I cleaned the CD, disconnected printer and CD-writer but still it is the same. What about the Automated System Recovery disk, can it solve the problem, if so from where may I download it? I am in the office now, and I should try your comments in the afternoon therefore, if you kindly give me a solution please check the message tomorrow. Thanks

"Only when it is booted from Win98 start-up floppy, it recognises the all drives as well as CD-drive. In this case when I want to install XP from CD it says: this program can’t run in DOS." What command are you typing in at this point??? Please tell me its not "setup" That happened to me as well, the command you need here is "winnt" that will get the installationg going
