what partitions does windows automatically create during instalation

Windows will create 4 partitions:

1. 450MB Recovery
2. 100MB EFI System (Hidden from disk management)
3. 16MB MSR
4. The rest is your C: Drive

Just follow this link to fresh install:
Solved Gone forever? - Page 2 - Windows 10 Forums

MBR and GPT must have an effect as my 250GB SSD has 3 partitions and is GPT:

450MB Recovery
100MB EFI
232+GB C:

This was doing a clean install deleting all partitions and letting the installer create the partitions it wanted.

Hey, Ztruker, are you sure you have no MSR? Disk Management won't show it, but diskpart commands will.

OK, thanks, Rich - it's surprising to me that a clean install would come out that way - every day I find a puzzle to attack here at TenForums. Any idea why you got this as opposed to the widely described and discussed inclusion of the 16 MB MSR for Win10 ?

Well. In one of his post, he deleted the 16MB MSR partition because he thinks it's not needed and saves 16MB..

@OP
For a fresh install. There must be 4 partitions as mentioned above

Now that you mention it, I do remember deleting two partitions I "thought" I didn't need. I'd completely forgotten about that. I used EaseUS Partition Manager and deleted the 16MB and 1.48GB partitions. This is what it looked like then:



Maybe I should do it one more time, only leave everything once I do a clean install after deleting all partitins on the drive and letting the Windows installer create what it wants.

Backup C:
Clean Install deleting all partitions
Restore C:
Fix boot error with Macrium.

That's what I did before and it worked great.
