Unallocated partition recovery

[noobie geek]

Hello everyone,
yesterday I needed to install windows 7 on my PC to do something but in installation process it didn't read my hard disk and somehow when i rebooted i found out that 3 of my partitions are gone including the C drive which has windows 10 installed on and 2 other partitions.
third party apps was reading 3 big unallocated spaces, fast forward to this moment, I now have the 3 partitions mounted as read-only using (Find and mount program) with the data on it ready to backup I assume. The problem is that i don't have much space to back up the data plus i want the old windows back and bootable is there a way to do something like extending one partition with the unallocated space without any data-loss in the lost partitions?

here is what the structure looks in find and mount.
there is another 289GB visible partition but for some reason it's not showing up

here another program

here is what it looks from the disk management tool i have no clue what is the 811GB partition and why are the space sizes don't match with other programs

first off your crippling your hdd's performance. every partition will slow the drive by 10% per partition.
your best bet is limit the drive to 2 maybe 3 max.
you set up the first to handle the o.s and your main programs. the rest as storage.
if you want to separate sets of data just use folders in the main directory of the second partition.

as the unallocated space looks to be directly in front of the movies partition so you should be able to extend that partition to swallow the raw unallocated space.
as for recovering data you can only do that to another drive. if you try to write to the same drive you will over write the data your trying to recover.

Whatever data you do have should be backed up before proceeding. Backup to a removable device.

So extending the movies partition will it have the data on the unallocated space ? or it'll just format it
Also if i take the old windows installation on external drive will i be able to make it bootable again after putting it back on the drive after the re partitioning?

Any one know what is the "disk 0 partition x" drives in disk management ?

 

[t53186]

Do not see partition x in the image of disk management. One other thing I did notice, it's not a good practice to use B or D as drive letters.

"... it's not a good practice to use B or D as drive letters..." While I totally agree with not using drive letters A or B for anything but floppy drives, I have been using C, D, E, F for years as drive letters with no problems. Ok, in hindsight, because I cannot see the submitted images, let me ask: is D being used for something unique?

 

[t53186]

D is your movies partition, that would be reserved for a DVD/BLU-Ray drive if you had one. You can use whatever drive letters you want, just mentioned is not a good practice

 

[RolandJS]

t - gotcha! Because I've been using drive letter I for my laptops' internal DVD/CD player/writer, I understand others saving D for such devices.

it will blank the data. the data has already been lost on that part of the drive as its been made raw and is now unallocated. it could possibly be recovered with recovery software but thats very hit and miss.

Thank you all for your suggestions and solutions I've successfully backed up the data on a friend's drive and extended the current partitions with the space
