View Full Version : [ubuntu] How to Convert HDD to Basic in Ubuntu

May 1st, 2012, 07:49 PM
While installing Ubuntu, my hard drive overwrote parts of Windows 7. My Hard Drive is a Dynamic Disk. While trying to reinstall Windows 7 Ultimate 64 bit, the install disc cannot find the Hard Drive. The BIOS can see the hdd and is able to boot into Ubuntu. I believe the problem is due to the dynamic disk type. Are there any tools that can easily change the hdd into a Basic or that can help with this problem? Attached is a picture of what "sudo fdisk -l" puts on the terminal.

A bunch of links, most seem happy with EASEUS. You should be ok as you only have 3 SFS and the extended. If you had more you would have to houseclean. Still best to have really good backups. And before doing anything make a Windows repairCD or USB if you have not, you may need it to repair Windows.

Dynamic volume is a Microsoft proprietary format developed together with Veritas (now acquired by Symantec) for logical volumes.
You may be use a third-party tool, such as Partition Wizard MiniTool or EASEUS to convert a convert a dynamic disk to a basic disk without having to delete or format them.
I've never used any of these and so I can't be sure they will work.Be sure to have good backups as any major partition change has risks.

Used EASEUS Partition Master - free version includes conversion
EASEUS Partition Master - The free home edition converted both dynamic partitions into basic partitions in less than 5 minutes!!

Several users have used this, it has a liveCD download to use but you have to use the non-free version:
MiniTool Partition Wizard Professional Edition 5.2 to convert without loss of data the disk from dynamic disk to a basic disk.
also used Partition Wizard to set an existing partition logical instead of primary
Converted from dynamic with MiniTool, & repaired windows

SFS converting:
Post 96 using sfdisk - must have only 4 partitions

The vendor recovery DVDs are just an image of your drive as purchased. If you have housecleaned a lot of cruft normally included, run many updates with many reboots, and added software you may want a full back up.

Another suggestion by srs5694

Make your own Windows repairCD (not vendor recovery):

Windows 7 repair USB, Also Vista if service pack installed
