Yesterday, I got my windows 8 BSoD on boot (reboot repeatedly) for "system thread exception not handled" so I can't do anything thus I installed ubuntu 12.04. still, I prefer windows for compatibilities sake...

But now I want to replace the windows 8 with windows 7 64bit ultimate. So, how to remove the windows 8 from my laptop using ubuntu because I still can't access windows 8 directly(still BSoD) and install windows 7 then?

do you have Windows on a separate disk? – Meintjes Jul 24 '13 at 12:32
yup............ – Vastor Jul 24 '13 at 12:33
yeah then just wipe the other disk in Ubuntu and install windows 7 on it. – Meintjes Jul 24 '13 at 12:35
This is a bit weird. I mean, to come on Ubuntu Q&A site and ask "how can I replace Windows 8 with Windows 7". Better would be to ask this question on a Windows Q&A site-forum. – NikTh Jul 24 '13 at 13:02
Has nothing to do with Ubuntu. Fix lies in using a bootable installation or recovery media (that can be any OS). – Rinzwind Jul 24 '13 at 14:39

I would use GParted to format the separate disk.

first you have to install GParted :

open a Terminal by pressing ctrl + alt + T

Then enter the following: sudo apt-get install gparted and wait until the installation is complete. After that type in the terminal sudo gparted and hit enter.

A window should open.

Follow the instructions in the link: Format a disk using GParted


My Tutorial:

  • Open GParted in a terminal with sudo gparted
  • In the upper right corner you can choose the HDD gparted enter image description here
  • Choose the HDD where Windows 8 is installed on.
  • Right click on the HDD (like in the foto) and choose Format to and then the File System you want it formatted in. I would recomend you format it in NTFS. enter image description here
  • After that there will popup a field at the bottom saying Format "Path" as NTFS. Right click and press Apply all Operations. enter image description here
  • Press Apply. enter image description here
  • Wait for the Operation to finish and your done. Your disk is formatted. enter image description here
