I've messed up with dynamic partitions and I need to backup

This 100MB partition has a purpose (some system boot files), it was created at the windows 7 installation.

The size is not exactly the same, I won't transfer everything, but I can afford to sacrifice some and prioritize other.

I've never seen a 100 mb partition shown as RAW. That would concern me. Your boot files appear to be on S.

But you apparently used a dual boot at one time, so who knows what that has left behind.

If you can't or won't transfer everything from F, then you can't delete it and therefore you could not extend into that space.

Or are you willing to make F smaller, without deleting it entirely?

I can transfer most of the dat that is on the F to the 244GB partition, not all, delete F, and extend S, will that work ?

About the 100MB partitition I searched on google and found some explanation about this 100 MB partition, here:

What's on that 100MB partition? Can I delete it?

Re the 100 MB partition. I know what it typically is. It's made by Windows at the time of installation and normally contains your boot files.

BUT--for whatever reason--your boot files on your current installation are NOT on that partition. It should NOT be marked RAW. Your boot files are located on the partition currently shown as "System", which is partition S.

You said in an earlier post that the 100 MB partition contained boot files. What specifically makes you think so? Your disk management picture says otherwise.

My boot files are on C, not on a 100 MB partition. But that's intentional. It works fine.

Unless you come up with more info, it doesn't appear that the 100 MB partition in your case serves any purpose.


You can delete F at any time you want. Move what you want from it elsewhere and delete it.

However----F is inside an "extended" partition represented by that green border. If you delete F, you still have to delete the surrounding extended partition. I think you need to use "diskpart" to do that. It's a command line tool available in Windows.

I guess it won't boot if I delete this partition.


Are you referring to the 100 MB partition?

What makes you think it won't boot without it??

Leave it alone if you want; it's not harming anything, but the "RAW" status is highly unusual.

Will I be able to extend to the free space that will be on the left of S: after deleting this partition ?

Yes, but it's only 100 MB and would not gain you much.

You could NOT use Windows Disk Management to do that. Windows Disk Management can extend ONLY to the immediate right of the partition to be extended. Not to the left.

You'd have to use another tool, such as Partition Wizard. It's excellent.

I would work on one problem at a time; first work on deleting F. After that's done, consider what to do about the 100 MB partition.

Diskpart is not difficult to use and can get rid of the extended partition. You could then extend S into that space using Windows Disk Management--because the space is to the RIGHT.
