I would suggest installing from a usb flash drive or booting from one. It's way simpler and you avoid wasting a cd/dvd. That's what I do. And BIOSes rarely have problem with that.
Yes it does, but it won't boot at all from the cd drive no matter what options are set in the bios, and there is no floppy drive, just one working usb port. It has Ubuntu installed on it which was installed from another pc. I want to install windows 95 or 98 on it (to run some old software) but windows won't accept being shifted from one set of hardware to another. I'll give the usb flash drive suggestion a try (would that work with an old OS?)does your bios have a boot other devices option ?
what o/s is on the hdd ?
I do have a 2.5" adapter. It's what I used to install ubuntu on the laptop's hdd. If I remember rightly I did try installing just dos on one try but that didn't work either bizarely, but linux doesn't have any qualms about readjusting to new hardware.
For somewhat old(9-12 months) hardware, it rarely has any trouble.
you should just connect the hdd to a pc with a floppy
boot from the floppy
and type sys c: (make sure the windows hdd is disconected do you dont accidently put dos on that)
