When that happens, it usually means Windows is already using 4 partitions on the drive. To be sure, boot computer again with live LL DVD. When up and running, go to
Menu -> System -> Partition Drives to open the
GParted program. Then take a screenshot of the
GParted window -- either hit <PrtScn> key, or go to
Menu -> Accessories -> Screenshot. Then follow directions
here to post it to the forum for us to see. Once we see screenshot, we'll advise you on how to proceed.
While waiting for a response back, boot into Windows and do the following to prepare for the LL installation:
- Make a set of recovery DVD's for the operating system. There should be a built-in program allowing you to do that.
- In Windows disk manager, defragment the "C:drive".
- After defragmenting, use disk manager to shrink the "C:drive" to make room for LL. Leave the space completely unformatted. Do not attempt to create any new partitions for Linux. You'll need to decide how much space you want to allot for LL, but try to give yourself at least 20-30GB for that.
P.s. If having issues trying to post the screenshot, try renaming it to something simple instead of using the time-stamp formatted name issued automatically by the screenshot program. (Right-click it and choose "Rename".) Sometimes that naming format causes problems with uploads.
P.s.s. Noticed in your signature "GPU: unsure what GPU is". GPU = Graphics Processing Unit. To find out what graphics card your machine is running, open a terminal while booted into your LL DVD and enter this command:
