I tried to delete my system reserved partition in Windows 10 in order to just boot from my primary partition, C, but now I cannot boot.
- Question from Superuser
The "deleted partition now won't boot" issue is common and you are not the only one who did this. Maybe you were about to set up dual-boot, or perhaps you simply discovered a partition in Disk Management with no drive letter, but it took up a lot of space, so you wanted to free it up.
No matter why you deleted that partition, now you were in trouble – you had the Windows boot partition deleted, and now you could not get Windows to boot.
What on earth led to the situation here? If you look up the root of this problem, what type of partition you have deleted is the key. For convenience's sake, hard drives (GPT/MBR) are logically divided into several partitions to store different types of data, facilitating users to manage their data.
The following illustrates the disk type and reason why deleted partition now wont boot. If you are in a hurry to get your Windows bootable, go directly toWindows troubleshooting in the next paragraph.
For GPT hard drive users, in default, you are supposed to have these partitions as follows:
On the one hand, EFI System Partition, also called ESP partition, stores the EFI boot loader and applications for firmware, which is necessary for Windows to boot – so you may have deleted this partition and led to an unbootable Windows.
On the other hand, primary partitions contain the files and data necessary for the operating system to boot; if you delete a primary partition that stores the boot files, the computer will be unbootable.
On the contrary, if you have removed a data partition, you can still perform GPT partition recovery with the help of partition recovery utilities.
For MBR hard drive users, by default, you will have these partitions:
On the one hand, the System Reserved Partition contains boot configure data and system boot files, and it was created when the OS was installed. The files in it are necessary and need to be intact. If you delete this partition, then the computer cannot boot.
On the other hand, the primary partition, which is used to store boot files, cannot be deleted.
In a nutshell, likely, you may have accidentally deleted EFI partition, SRP partition, or primary partition, which contains boot files and is necessary for system startup.
