I have Ubuntu installed on hdd, recently I've converted that disk to GPT using gdisk and created EFI partition formatted in fat32 (right after convertion it was ntfs, but then I've formatted it into fat32). However, when I was trying to install windows to unallocated space on disk, it said that my ESP is not in Fat32 and asked me to format it into fat32. I have rebooted into ubuntu and checked partitions:
- ESP created during convertation to GPT (fat32, about 4 Mb used, 200 Mb unused)
- Restore partition created by windows (ntfs)
- ESP created by windows (fat32, about 4 Mb used, 96 Mb unused)
- MSR partition created by windows (unknown)
- Partition for data created by windows (ntfs or unknown, I do not remember)
- Linux swap
- Ubuntu partition
Windows version is 10, ubuntu is 16.04, I also have Ubuntu live USB in case I have to fix bootloader or something else. How can I fix the error?
EDIT: Now I've deleted the EFI partition and Ubuntu can still successfully load, also Windows now does not give error about ESP but it does not create one! It only creates Basic data partition and MSR partition, no ESP and no Recovery! It does not load after install, however Ubuntu loads because it has GRUB on my old HDD with Windows (this HDD is half-broken that is why I want to reinstall Windows to another HDD). I have literally no idea what is happening, any suggestions?
What do you mean by
create the efi partition within the windows installation

I can't understand you, do you have the solution or are you just saying that you had this problem and couldn't solve it? – Krigga – 2017-05-01T08:17:11.153
i had the problem and the problems were that i was using a gpt partition table and that i pre created the partitions in ubuntu. – Nadav Tasher – 2017-05-01T08:31:32.483
I have already tried deleting efi partitions, creating them, formatting them, etc, nothing helped – Krigga – 2017-05-01T08:40:06.890
try to create a new partition table from windows installation – Nadav Tasher – 2017-05-01T08:41:19.507
1what do you mean by "windows is yet to implement gpt"? Windows has supported booting from GPT since Vista and using GPT data drives for even longer than that – phuclv – 2017-05-01T09:17:02.487
when i use gpt flash drives on 7,8.1, and 10 they wont recognize the drive – Nadav Tasher – 2017-05-01T09:18:18.063
I have tried pressing on unallocated space on windows installation, it creates 4 partitions including efi if there already was one efi partition but then gives error, or it creates only 2 partitions excluding efi if there was not one efi – Krigga – 2017-05-01T09:25:25.323
just remake the windows installation flash drive or install without uefi – Nadav Tasher – 2017-05-01T09:26:24.223
