Haven't used Linux in about 4 months because I got fed up trying to solve this problem (and i was on holiday and had no computer.)

I can install from a live cd but when I boot into Linux i get a message that the device cannot be found.

If i dual boot with windows (regardless of version) the CD ROM also disappears. Its down to LILO and GRUB.

I heard that its down to ACPI Settings and i have fiddled around with them to try and fix it but its no use. I cannot work this one out.


Experimenting with Mint Linux which is basically ubuntu. Does it will all distros from Portage, DEB and RPM based distros.

By the way i'm usung a Laptop ROCK CTX PRo,

2 GHz Core 2 Duo
2GB Ram
160 5400rpm SATA HDD
Geforce Go 7950 GTX (a pain to set up)


Can anyone help, Thanks

I just had a similar problem. I fixed it by specifically setting the jumper on the CD drive. I had two, one on secondary master and one on secondary slave. I had been using them with the jumpers set to cable select, but for some reason it started flaking out. So I tried setting the jumpers to master on the master and slave on the slave, and it worked great. Hopefully it'll work for you too.

There are no Jumpers on the drive, its just a standard laptop drive. I know that its definitely down to the bootloader.

Are there any GRUB or LILO settings which could effect this?
