I installed Windows Vista Ultimate and Ubuntu 9.10 on my computer. Now, I wanted to replace Windows Vista with Windows 7 without losing my Ubuntu 9.10. I tried to reformat Vista so I overwrite it with Windows 7. Since then, I started getting an error message. I noticed that my Drive C and Drive D have merged together giving me a bigger unallocated space. I have parted them again using my Ubuntu and Windows 7 installation disks but the resulting partition is only one and still giving me the same error message. I believe the partition only contains my Ubuntu. I tried formatting it again but I was still unable to do it correctly. Please give me an advice on how to format my Windows Vista with Windows 7. I wanted to keep my Ubuntu. Thanks.
Dual Boot PC: Error on Replacing Windows Vista with Windows 7
Ubuntu has a partitioner named gparted. You can get this by going to applications>terminal and typing (sudo apt-get install gparted) without the brackets. This program allows you to see the partitions on your hard drive and create new ones. If you are installing Windows 7, for security reasons I do recommend creating a NTFS partition. Have a careful look at the partitions on your hard drive. You can erase the windows partition and re create a NTFS blank partition of a size that you'd like the entire partition to be. Do yourself a favor and try to name this partition. Otherwise, take full notes of what each partition is, what the size is and the format of it so that when you come to install Windows, you don't accidentally overwrite Ubuntu!
Now that the partitions are created, insert the windows 7 cd and reboot. Remember to change the settings in BIOS to allow the CD drive to boot first. Once Windows 7 cd has loaded and is ready to install, select the partition you created (the NTFS one) and install Windows 7 on there. Once the installation is complete, reboot the computer (remember to take out the CD when Windows is FULLY complete) and as the computer starts up, the grub loader of Ubuntu will load up.
So if you have followed the above instructions correctly, you should have both Ubuntu and windows 7 on the hard drive but in separate partitions. I hope this will recover your problem.
