Windows 10: Change active EFI partition

Hello,I am trying to update the BIOS on my laptop but it says 'esp disk space not enough'. I noticed that I have 2 efi system partitions: one is 1 GB and is on the SSD where the OS is installed. This is completely free. The other is 100 MB and is on an HDD and this seems to be active as it has used space. Is there any way I can make the bigger one active, or extend the smaller one?I tried to extend the smaller one from an elevated cmd but it says: You may not extend OEM, ESP, or recovery partitions, or, offline volumes. The volume you have selected may not be extended. Please select another vo

Move EFI partition

its to enable win 10 to update to its anniversary edition.. it cant do this due to lack of C drive space i have had a quick try with the trial version of easus.. it didnt seem to be able to do what i want..

i am assuming i cant just delete the efi partition but maybe i could.. as yet i havnt even figured out how to get into the bios of the thing.. maybe that should be my next step.. *Smile

diskpart could probably do it but figuring out how (it aint that user friendly) might be difficult without step by step instructions..

Windows 11 EFI Partition

Hi Brian,

Thank you for the screenshot, you have created a 100MB EFi partition on the dive that contains the C drive, is that correct?

If it is, follow the steps provided by Kyhi on the link below to make that the active EFI partition, then in BIOS you would need to change the boo order to that drive.

Blank EFI Partition

I have an ASUS R558UR.

I had windows 10 installed on my laptop and I decided to again have a clean install of windows 10. I booted from USB and cleaned windows partition i.e. C drive and also cleaned EFI partition. I reformatted Drive and it had also created EFI partition of 100
MB. I installed windows on laptop and setted that up. After installing windows my laptop it started taking a long time to boot about 90 seconds but earlier it took only 7-10 seconds. After analysing everything I found that my EFI partition is blank.

Please suggest me how to write back EFI partition so as to reduce boot times.

Thanks in Advace.
