Cant find EFI partition [Solved]

Hi,
I am installing arch linux on my computer, that has an existing windows OS. When I am looking at the output of fdisk -l /dev/sda, I dont see any EFI partition.

Here is the output of fdisk -l /dev/sda:

Disk /dev/sda: 232.9Gib, 250059350016 bytes, 488397168 sectors
Units: sector of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal):  512 bytes / 512 bytes
Disklable type: gpt

Device              size     type
/dev/sda1          500M  Microsoft basic data
/dev/sda2          130G  Microsoft basic data
/dev/sda3          480M  Windows recovery environment
/dev/sda4          8G      Linux swap
/dev/sda5          40G    Linux filesystem
/dev/sda6          54G    Linux filesystem

Where can I find the EFI partition?

Also, I found out that windows was hibernating instead of being shutdown (even though I disabled the fast startup option), will that cause a problem?
Thanks

From that, it doesn't look like you have one. Are you sure Windows was using UEFI?

Edit: unless it's on another disk.

I don't think it uses UEFI, it had "Legacy" in the bios mode in msinfo. Oops

Edit: Windows now doesn't want to boot.... I guess I will reinstall it, I guess I can put a solved in the title. Thank you for your help.

It would appear that you converted the disk from MBR to GPT, it's no surprise Windows wouldn't boot.
