I want to dual boot my laptop, but Windows doesn't read the Ubuntu DVD. It doesn't recognize it, nor a Linux Mint DVD.

Two days ago I installed Mint 13, then removed it because of installation errors, and changed some stuff using EasyBCD. Now it doesn't read the Linux Mint DVD. It doesn't recognize it. I can insert any game DVD and it works, but the Linux Mint DVD and Ubuntu DVD doesn't work. I think it's some BIOS error.

I can't access my BIOS. I tried all the F function keys and none of them work. How can I fix this?

update

i was finally able to boot ubuntu, but it freezes, after bootimg, it shows me the purple screen and then it shows me a black screen and it freezes

Looks like there are two independent problems.

  • Reading the discs
  • Accessing the BIOS setup

Reading the discs

Did these discs work before in the same drive? I suppose they did but you did not make it clear. Do these discs still work in other drives. Since you probably burnt the Linux discs yourself: Have other discs (especially of the same brand) that you have burnt recently also stopped working? The drive might just be worn out/dirty so it finally has crossed the limit where it completely fails. This limit is usually reached earlier for burnt discs and especially for discs burnt with the already degraded drive. This could also explain why your previous install attempt has failed: While it was still able to read some parts of the disc it already failed on others.

Accessing the BIOS setup

Are you sure that you have to press some F key? The Del key is also quite common. There should be a message on the screen on which key has to be pressed. Otherwise check the mainboard manual. If the correct key still does not work, you might want to try another keyboard. If you are using a USB keyboard, also try another port. Ports on add-on cards and USB 3 enabled ports might not work in this situation.

Well at least you had some success in booting, but freezing monitor issue. Two possible alternative I can think of:

  1. If you are trying to use Ubuntu x86_64 (64bit), installation may freeze because of nVidia graphic card issue.
  2. Your success may come largely from installing Ubuntu 386 at 800x600 resolution. Once you achieve that, update the nVidia (not freeware) driver. I had similar issue with my workstation where Ubuntu failed to install, but Sabayon 9 (64bit) worked quite well. Finally I ended up with what CERN uses -- SL6.

you may also want to try burning ISO at lowest speed. I know it will help, as it did to me.

you can try to install linux from hard drive. Here is tutorial how to do it.

If you can't set to boot off dvd or usb you don't have much options.

  • Can you check the integrity of DVD? It is possible that even a small speck of dirt can prevent the whole DVD gone useless.

  • Another factor could be you burnt the ISO file at max speed. If you burn the ISO at lowest possible speed (say 2x or 4x) then the disc will have much less error in reading when it reads. I had similar issues in early generation linux (Ubuntu, Fedora and Mandrake).

  • You could use Nero DriveSpeed to make sure your DVD never become unstable at high speed (or low speed).

  • Are you using same DVD drive to read and write?

  • What Windows version are you using? ANY Windows stability issue?

This shows that your GRUB is corrupted. If you edit and re-install GRUB, you can recover both installed OSes.

However, if you want to recover Windows and Linux data, you can use Partition Find and Mount

You can try to remove CMOS battery and reset the JUMPERS. Allow at least 10 minutes before restarting the PC to remove all static charges if humidity is low, otehrwise electrostatic charge can damage your PC.
