View Full Version : [ubuntu] Four Primary Partitions

January 3rd, 2011, 03:23 PM
Brand new member looking for help please.
I've been playing with Ubuntu 10.10 on pendrive, but cant find a way to save settings for bluetooth, or wireless, or keyboard UK. etc. So read through a few articles about installing, looked easy enough til I see something regarding 4 primary partitions, which come pre-set up on my HP pavilion dv6.
These are:-
Recovery (D:)

Can I dual boot with this setup or not ?
Can I save changes when running from pen drive ?

Following is info I understand is required for diagnosing problems.
Windows 7 is my current O.S.

Thanks Roy

Welcome to UF :-)
If those are all primary partitions (and it's likely that they are) you would need to delete one of them before creating an extended partition in which other operating systems can be installed.
If you go to the Windows disk management console you will see your 4 partitions displayed. Primary partitions have a thick, dark blue line at the top of each partition, in Windows.
Others with the same setup as you have deleted the HP Tools partition, then shrunk their C: partition (in that same disk management window) to leave unallocated space for Ubuntu to install into.
The HP Tools partition has diagnostic programs in it, which, I believe, can be downloaded separately from HP.

If you choose this method, you should first defragment the C: drive at least once, and preferrably twice, before shrinking it.
After shrinking, you should reboot Windows once or twice to make sure Windows is happy. It can be funny like that :-)

Thanks Quackers, so I'll see if I can get these tools for HP then follow your advice.

Thanks Roy

That worked as you said, so now dual boot, with 64 bit Ubuntu. Don't know why I'm offered Vista at log on but the Windows 7 and Ubuntu both work, so thank you Quackers
