I tried to install Fedora 17 on the same disk I have Windows 7. First I got the message, that there are no free space to create partition, even in Windows part of disk was marked as unallocated. I spent two days to get to know that there's something like dynamic disc. OK. I converted it to basic one using EaseUs tool, which took about 20 hours. Ok, no problem. Now I have basic partition, but Fedora (also GParted) didn't see it. It acts like there was not any partition on my disk and wants to wipe it. I don't want to lose my Win7 partition and data. What should I do?

This is how Win7 sees it (sorry for Polish language): http://i46.tinypic.com/259ansz.png

This is how GParted sees it: http://i47.tinypic.com/i3c5dv.jpg

Message from Fedora is:

"We could not detect partitions of filesystems on this device. This could be because the device is blank, unpartitioned or virtual. If not, there may be data on the device that can not be recovered if you use it in this installation. We can remove the device from this installation to protect the data."

I'm getting really frustrated wasting my time on such stupid things. I have no idea what to do. Can anyone help?

Could you paste output from fdisk -l /dev/sda from GParted LiveCD? – pbm Sep 12 '12 at 18:53
In alternative you can post the output from parted /dev/sda print, but fdisk is fine, too. – Francesco Turco Sep 13 '12 at 9:47
It's more than a year after this question was asked... if you're still around, could you try it with the current F20 release? – mattdm Dec 18 '13 at 12:31

Something you could try:

  1. Cut off a section of the last logical drive, in your case G:\ You can do "Shrink Partition" from disk manager, and shrink the last drive by around 50-60GB. (minimal space for the Fedora installation)

  2. It should show up as "unallocated space" and have a Green coloured strip. Then retry the fedora installation. See if Fedora can detect that space.

  3. Please do not convert that unallocated space to any windows partition. Just shrink the last drive, and try if fedora can use that space for installation.
