I'm working on a pal's IBM PII computer which was extremely slow so I tried to format it but now I cannot boot from CD . I have check all setup BIOS but nothing shows or states how to change the boot sequence. Can anyone help pls.
More than likely it doesn't support boot from CD. That is a feature that was not implemented in a lot of older computers. You need to boot it from a floppy. Search online for win98 boot floppy or find the original win98 setup floppy disk.
Yep, that's how things used to be. In a clean machine there are no CDROM drivers, so that's why you can't boot from it. The Win 98 floppys Mike mentions install DOS routines and a generic CDROM driver. Amongst DOS is FDISK for proper formatting and partitioning before installing Windows. Your CDROM may now appear as an odd Letter, look carefully at the text on screen, and you may notice it telling you that CDROM is drive R: or some such random letter. Type R: to get onto the drive, then you can type Setup and away you go.
Just a warning - last time I downloaded floppy boot disks from the Interweb, most of them (95 and 98) wouldn't work, don't know why. Could just have been my PC or the disks. Anyway I have one here that definately installs Win98 so if you have any bother I can email you a copy.
William is correct that there is a utility on the Windows 2000 (and XP) cds for creating the set of floppies required to initialise the setup process if your system can't be booted from a cd. AFAIK there was no such utility on the Win98 cds.
To the OP: I am surprised that a P-II system does not support booting from cd. Be sure that your cd was made to be bootable. If it is an original operating system cd it should be. If you cannot find where to change the boot sequence there is often a hotkey that you can press at boot time to give you a menu of bootable drives to choose from. IIRC on IBM systems you need to press F12.
replace "invalid" with "uk" to reply by email
With win98 and earlier, yes. Use the boot floppy to load cdrom drivers and format the hard disk (if necessary), then just enter "D:\\setup"
Assuming that the cdrom is mounted as D:, of course.
Many computers from that era were supposed to be bootable from CD, but weren't. Presumably this came down to limitations in the BIOS's cdrom drivers. Seldom a problem in newer equipment.
As to boot images not working, the chances are very high that the disk, or drive, or both are faulty. I always found floppy disks to be a very delicate medium, with frequent failures of both disk and drive.
Did you consider using 'disk clean up', defragging, or inspecting the number of programs automatically loaded at start-up ? Norton AV is a system performance killer for example especially on a PC of that vintage.
Is the CD drive even listed in the boot sequence options ? Booting from CD wasn't always possible.
