Hi, i have on my computer a 250gb C drive on which i had installed windows XP. I also have another internal 80gb E drive on which i have installed windows 7. I decided that i didnt want Windows XP and as i didnt have anything else on that C drive i used Killdisk to completelp wipe that drive. When i now start the computer i get the massage " disk boot failure : insert system disk and press enter " ' and cant go any further. When i put the windows 7 install disk in the drive and go to the repair option , i eventually get the message "root cause found : partition table is corrupt on disk/device/harddisk0-repair action-partition table repair".I dont know what to do to get the computer up and running. Is it because the OS is on the E drive and not the C drive . Hope you can help. Thanks . Trevor (janvor50@internode.on.net)

If you have two physical disks present in your machine, are these PATA or SATA disks? If they are PATA disks & you currently have the 250GB connected & jumpered as the Primary Master & the 80GB as the Primary Slave. I would suggest you reconnect & jumper the disks appropriately, with the 80GB setup as the Primary Master & 250GB as the Primary Slave & confirm this in the BIOS. Once that is done, just rewrite the MBR using your Windows 7 disc to fix the machine's bootloader. Windows 7 News!

If the drives are SATA check the boot order in the BIOS to make sure the 80GB is the first boot drive. When you installed Win 7 was the XP drive in the machine? During setup if Win 7 sees another drive with an operating system, XP or Vista it will configure the system as a dual-boot and when you blew the XP disk away the boot program is looking for the XP drive. As Sabertooth stated insert the Win 7 disk and fix the bootloader so only the Win 7 is the boot OS. Richard

Hi, thanks for the replies. I have physically checked the drives . The E drive is the 80gb drive (with W7) which is Western digital PATA (IDE). The other is the C drive 250gb(wiped clean) which is a SATA. The PATA drive links to the DVD and then to the motherboard and the SATA links directly to the motherboard. When i gi to the BIOS , under standard CMOS features it shows - IDE channel 0 master wdc wd80. -IDE channel 0 slave dvd - -IDE channel 2 master wdc wd250. On advanced BIOS features - hard disk boot priority 1 ch0 m wdc wd80 2 ch2 m wdc wd250 3 bootable add in cards. Also shows- first boot device hard disk, second boot drvice hard disk and third boot device cd rom. Under CMOS features , is the channel 2 supposed to show IDE or SATA and is it supposed to be primary or slave ? If so , how do you change them ? Hope this helps to advise me further. Trevor

in deleting the old (C:/) drive you probably deleted the start up or MBR Table, pop in the win 7 dvd and follow the advice already given, or do a full install on the 250 gig drive which is probably faster than an old 80 gig drive. i hate computers! but cant help myself....
