Hello

my 512 GB SSD was splited in two partionn C and D drive. As I was runnig out of space, I decided to delete D. I couldn't do it with Windows Disk manager interface so I used DMDE.

I took the drive out, I put it into a SSD -> USB enclosure, I opened DMDE, selected the external drive and I delete the DATA partion. When doing this, is ask me if I want to make a backup and I agree.

I've put back SSD but PC doesn't boot anymore. I've put the SSD back to enclosure, load the saved file but doesn't work. There's a red E on DMDE. It seems to indicate a entry error in partion. I don't know how to fix it.

I've read some post on redit asking to insert back partiton, I 've tried but didn't help. I've attached a pics of the drive how it looks currently and backup from DMDE. It should be probably easy to find the right command but I don't want to mess up more.

Thanks
Sam

The protective MBR partition metadata are missing from the end of sector 0.

Thank you very much, this is a great site to understand the structure. What would you recommand to expand/shrink/delete W10 partition, DMDE or something else ?

I prefer gparted for that sort of thing - but make sure you have an image before doing anything, don't work live on a drive - accidents happen.

Thanks, I did it with Gparted, perfect.

I think the solution in DMDE was probably to toggle GPT On/Off. This would have reset the protective MBR.

I've tried that but didn't work. I did it manualy.

BTW, any suggestion for a backup software who could backup daily my SSD 512 GB (Document and Desktop) to my WD 1TB SATA installed on same computer ? Or Sync tool... but something really easy.

Maybe easeus to do backup? Not sure if its free and how to use it tho...

Have a look at syncthing

Thanks. I've checked and syncthing is good to sync local PC with remote. To Sync internal HDD on same computer, it's not really designed for this. so I took https://freefilesync.org/download.php
