GRUB Windows 10 and Arch Linux!

Hi!
I want try install Windows10 and Arch Linux on 1 PC and I have small problem

First I install Win10
/dev/sda1 - 500M - Windows create boot for WIndows
/dev/sda2 - 800G - Win10

And I do gdisk /dev/sda
/dev/sda3 - 500M - /boot ext4
/dev/sda4 - 200G - / ext4
/dev/sda5 - 2G - SWAP
/dev/sda6 - ALL GB - /home ext4

Now I configure and install system and try install grub:

pacman -S grub
grub-install --target=i386-pc --recheck /dev/sda

After that I have error:

Installing for i386-pc platform
grub-install: warning: this GPT partition label contains no BIOS boot Partition encoding wan't be possible.
grub-install: warning: Embedding is not possible. GRUB can be installed in this setup by using blocklistsHowever, blocklists are URELABLE and their 
grub-install: error: will not process with blocklists

Can You help me?

Windows+GPT normally means you have a UEFI system, so is this UEFI or BIOS? If UEFI, why are you following the BIOS install instructions?

I guess he just converted it from MSDOS/MBR to GPT with with some disk utility...normally Windows installed in UEFI mode will have 4 partitions instead of 2...

If you have the correct table type for your firmware, i.e. UEFI with GPT, then your /boot partition has to be formatted as FAT32, not ext4.

Re: GRUB Windows 10 and Arch Linux!

As we seem to be playing a guessing game here, my money is on the OP attempting to install a non-UEFI system after a GPT conversion.

*If* this is true then creating a BIOS boot partition (type "EF02" in gdisk) will allow GRUB to be installed to the GPT drive.

His Windows won't work with GPT. At best he has to switch back to MSDOS/MBR, but the boot code might have been corrupted anyway.
