Legacy Bios and System Reserved Partition. Two scenarios...

I'm a little unsure on this and so I'll ask...

I understand what the system reserved partition does, and how the system reserved partition gets created when you clean install onto an unallocated HDD/SSD.

Question.
If at some future point Windows is reinstalled (and a specific example here) by using the MCT (Media Creation Tool) and booting from the MCT and doing a Custom Install onto the pre-existing C partition, what happens to the functionality of the pre-existing system reserved partition?

Is it now essentially defunct and serving no purpose, or can/does the new installation make use of it?

Hi There

The system reserved partition contains the boot manager and the startup files for encryption technologies, i.e. bitlocker.

So, i guess in answer to your question: Regardless of a custom install or not, the windows installation will overwrite the system reserved partition. If you delete it, windows will not boot. I found this out the hard way....

However, if you don't need or want it, you can omit its creation when performing a clean install.

Hope this helps

Thanks. What you suggest sounds pretty definite in that the new installation does overwrite the old system reserved.

No worries, happy to help
