You must have the system set to "Boot from CD-ROM" in BIOS Setup, as first boot device, and have other boot devices disabled. Simply change the setting to enable the system to boot from hard drive.


Could very well be one of several or a combination of many different problems at play here. Catweazie has the first one covered.

For the second, download Memtest86 @ http://www.memtest86.com/memt31a.zip and it will create a bootable floppy for you, then take that back to your sick comp and let that sucker run for a good 8hrs to check all your physical memory.

If that doesn't turn up anything, check out the manufacturer of your hard drive, then go to their website and download the utility software for that company:

Maxtor @ http://downloads.maxtor.com/_files/maxtor/en_us/downloads/powermax.exe

Seagate @ http://download.seagate.com/seatools/registration.nsf/desktop?openform

Western Digital @ http://support.wdc.com/download/dlg/DlgDiagv504c.zip

Fujitsu @ http://www.fujitsu.ca/download/hdd/FJDT620.EXE

Samsung @ http://www.samsung.com/Products/HardDiskDrive/utilities/attach_file/Shdiag.exe

most of those require you to again have a bootable floppy than will run these programs from a fresh command shell.

Then if all else fails, the last, and probably most common solution to this type of problem...... file copy errors from the CD drive, caused either by a scratched disc, or dirty lens. But clean both anyway, (the CD-ROM should be dismantled and the laser gently rubbed with a Q-Tip and a tiny but of ISO Propyl)

Hope This Helps!!!
