My 8.1 system was setup with a 2x cdrom. Not fast but it worked. Since burning was not possible with this cdrom I recently bought a 52x24x52 cdrw which worked okay until it failed. No problem because it is still within the guarantee period. For the time that I have to wait for replacement I was given a 40x cdrom in order to be able to work with cd's Funny thing is that with this cdrom I am not able to read my 8.1 installation cd's. On some other data cd's it will work but on cd 1 it will not recognize. After a reboot with this disc in the tray it just ignores the cd and starts Grub. The same disc in my 2x cdrom on a reserve computer boots as before so the cd is still okay. Can somebody with more expertise on cdroms give me an explanation? -- NTReader v0.36w(P)/Beta (Registered) in conjunction with Net-Tamer.
