converting primary to extended ntfs

Postby wizzleme » Wed Dec 21, 2016 5:57 pm

Thanks to all here for your help. Once I have things set up I won't be asking so many questions.

4 primaries here on a single hard drive winrecovery(hidden) c:win7boot d:data bootitbm embr

I would much prefer not to change to more than 4 primaries. So I would like to convert the d:\data partition to extended partition so as to resize it and split it up into more than one (logical) partition.

How to best/easiest accomplish this with bootitbm?

If possible please give specific steps in the procedure as I am somewhat of a dummy when it comes to partitioning drives.

Thank you.

I don't know if this best, but, if it were me, I'd:

1. Backup the d:\data partition.
2. Delete the d:\data partition.
3. Create a new extended partition in the now free space formerly occupied by the d:\data partition.
4. Create one logical partition in the new extended partition.
5. Restore the d:\data partition to the new logical partition.
6. Resize the d:\data logical partition and create additional logical partitions as desired.

Assuming the hard drive is now fully allocated, I don't know if the extended partition so created will be as large as the current d:\data partition. If not, it might not be possible to restore the backup of the d:\data partition into the smaller space. To minimize that possibility, I might either select "compact" during the backup of d:\data or resize d:\data smaller before backing it up. The choice between these is probably insignificant. I guess I'd back up d:\data as is for safety and then back it up again with "compact".

Thanks for the reply Bob. Can extended partitions be created under NTFS file system even?

D:Data is about half full so resize then backup then delete and created extended partitions seems the safest way to go. Not sure I trust "compact" never used that before, wonder if it is reliable.

"Can extended partitions be created under NTFS file system even"?

I'm not sure I quite agree with that wording, but I think I'm nitpicking. An extended partition, as far as I know, doesn't have a file system. The logical partitions/volumes within an extended partition can certainly be NTFS. I have some.

Compact: I tried it once just as an exercise and it seemed to work OK, but I have no experience of note. I certainly can't see anything wrong with making the other choice.

Yes. The file system type does not have anything to do with the
partitioning possibilities.

MBR disks are limited to 4 partitions, they can be 4 primary
partitions and three primaries with an extended partition. That
extended partition can contain any number of logical partitions.The
filesystem(s) used to not affect that.
