When CDROMs age they can lose the ability to boot but work fine in other ways. I keep a laptop CDROM drive handy to test for that issue.
I have an Acer Aspire laptop and installed an 80 gig. Seagate HD. The failed one was an 80 gig. western digital. I have set the CMOS to install windows from the cd-rom, the CMOS are very simple and there isn't much else that can be done there. I thought that the new HD was broke so tried another one and I still get this message "no operating system found". I'm wondering if Acer has
the bios programed for just them to install the HD?
I just don't understand whats going wrong, then I put the Windows disc in the cd-rom I hear it spinning then it stops and says no operating system found. Any ideas what going wrong here?
