I'm trying to fix a friend's Laptop. Its a Dell Vostro 1500.
The Cd/DVD Rom doesn't work for long time. So, I connected a USB CD/DVD rom and tried to boot the laptop using the USB rom. But when I use "F12" to select the boot source, it doesn't show the external USB CD/DVD Rom but it does show Hard Drive, CD/DVd Rom(*built-in) and NIC.
So, Can anyone please tell me how to fix this? How I can set it in BIOS so that I can boot from the external CD/DVD Rom?
* I tried different USB port and it didn't work and also I checked the ROM in another PC and its working just fine.
