Question: How to convert Triple boot to Dual Boot

Hi ya,

At the moment I have Win7, BT5 R2 and Ubuntu 12.04 installed in my HDD and everything works fine. I now need more space for BT and like to remove Ubuntu so that my computer becomes Dual Boot.

Can someone be kind enough to suggest how I can achieve that please? I am worried that my Grub will be completely messed up and I will not be able to boot. I know that I can re install BT5 R2 and while installing I can use the partition manager to claim more space for BT and delete Ubuntu and my laptop will work just fine. However I do not want to do that as there had been a lot of customization in my current BT set up and I do not intend to redo that again.

Regards

Hannah

If you installed the BT5 as the third OS, this is, the last OS you installed was BT5 (W7, Ubuntu and BT5, in this order), no problem, download gparted live cd, boot with it, erase the Ubuntu partion, then resize the BT partition, and then reboot.

If you installed the W7, BT5 and then Ubuntu, in this order, do as mentioned before, only this time you will need to recover the grub. In this case you will also need a live cd from any linux distro: Debian, Ubuntu, LMDE, etc. and then recover the grub..It is easy..

Hope it helps.

Luck...

It is indeed in this order.. Win7, Ubuntu then BT5..Good to know that it can be done..has anyone else done this before..

thanks

Well, to recover the grub it is not so easy, it happened with me and followed couple of tutorial how yo recover or update to grub2, but it didn't work with me as it must be.
Why you don't use monoarchive to back up the backtrack just in case of any problem

Disregard all the other replies....fml

Boot a liveusb of backtrack
Download gparted
Run gparted
Delete the partition u want to remove
Exit gparted
Install grub to /dev/sda (assuming /dev/sda is your harddrive)
Done.

Ok I got it. Now in addition to Deleting the partition, I also would like to add that deleted partition to my current BackTrack set up so that I get more space. Should I do that under gparted before exiting.

Also can you please explain " Install grub to /dev/sda (assuming /dev/sda is your harddrive)" part once again please.

---Gparted will do that for you..... Click the partiton and find the expand option....

Fair enough.. I deserve that...have a good one..

Ok after much trial and tribulations this is what I have done:

1. Removed 2 other OS from from Extended Partition
2. Make these 2 unallocated space as 1
3. Moved this unallocated space next to my BT5 partition (Primary Partition)

This is how my current partitions look like.

This is my current partition table:

Task: My BT5 partition is on 33GB and now 99% full hence I like to add that extra 38GB unallocated (/dev/sda4) space to my BT5 (/dev/sda3). Have looked into gparted Live CD but unable to add this unallocated space to BT5 volume.

Someone please suggest how I can do this.

Note: BT5 (/dev/sda3) is Primary Partition
& 38GB unallocated (/dev/sda4) is Extended Logical.

Regards

Certainly you should have done something wrong during the process. I do it very often and always comes up in succsess...I invite you read more about grub2...It is quite interesting. If I can help you with any doubt, let me know, I'll be more than glad to help you.

Need to read official tutorials..They are very clear and straight forward. Simple..

Luck...
