Forgot to create partition when installing windows 10

[hong1204]

 

Hi,

I just bought a new ssd and installed windows 10 on it. If I recall, during the setup there should be page where you select which drive to install windows on, and there's an option "New" to create system reserved partition and recovery(?) partition. I did not press "New" and went straight to "Next" to install windows 10 on it. Now my ssd just have 1 big partition. My question is will there be a problem without those partitions (system reserved, recovery) created? Should I delete and reinstall windows 10 again?

what model ssd is it, cause if it's a samsung, you can probably use samsung magician

Make it dynamic, shrink to 50-100 GB, create secondary partition on the empty space.

No problems really except it would be inconvenient to reinstall OS in the future should you need that because you'll need to backup your user data, if you have secondary partition it will be easier.

I didn't try that. But I did reinstall windows 10. Turns out after I pressed "new", the setup created 2 partitions: 1. 16mb system reserved partition, 2. another with rest of the storage for windows installation. It didn't create a recovery partition. When I open disk management, it shows the same as previous one. Kinda wasted my time .

 

Can you explain what shrink partition does?

That's perfectly fine, it does what it needs on its own.

 

Unless you have a specific need for another partition you're good.

you got to delete all small partitions from prev install, otherwise you may see more & more of them..

 

you just go to disk management , click on the drives & play with available options, some may be protected by sys by default which makes a little more work

but shrinking is very straight forward, to cut down unused space and leave as unformatted

Alright for those who still follow this thread, I'll provide an update.

 

So after I reinstall windows on my new ssd for the second time, I went to reformat my old ssd. That made my PC unable to detect boot drive when I restart. So I went ahead to reinstall windows for the third time, and I did it successfully.

 

Things I did differently:

• I unplugged all other old hdd and ssd, left only the new ssd plugged in to install windows
• I chose UEFI usb installation media tool, instead of legacy/normal one.

During third install when I press "new", windows setup create a 500mb+ system reserved partition instead of 16mb for the first and second install.

Aha, once you say everything....

 

There was already a boot partition on your 2nd SSD so Windows didn't need to make one on the new one, it just added its entry to the existing one. 

 

That's why you disconnect all drives but the one you want to install on before starting a clean install.
