[SOLVED] Grub problems

So
my friend tried to install Arch after I recommended it to him (I assumed
he knew what he was doing) but the installation was all messed up. I
told him to give me his computer and see what I could do.

First, when I ran fdisk the following message popped:

WARNING: fdisk GPT support is currently new, and therefore in an 
experimental phase. Use at your own discretion.

I didn't pay attention to it since I assumed that was just in case I
wanted to make a GPT partition.

I went through the installation normally until I installed Grub. When I
did the install script:

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

I got this output:

/usr/bin/grub-bios-setup: warning: this GPT partition label contains no 
BIOS boot partition; embedding won't be possible.
/usr/bin/grub-bios-setup: warning: Embedding is not possible. GRUB can 
only be installed in this setup by using blocklists. Ho
wever, blocklists are UNRELIABLE and their use is discouraged..
/usr/bin/grub-bios-setup: error: will not proceed with blocklists.

[EDIT] I have all partitions mounted and everyone of them was made in
fdisk using the 'n' option (create new partition) and not the 'g' option
(create empty GPT partition table).

Re: [SOLVED] Grub problems

Sounds like the disk is already setup for GPT. If you want to switch back to MBR, you'll probably just want to start over.

I deleted all the partitions before writing them, in fact, I did everything as if I started a fresh install. Also whenever I try to boot it just shows "GRUB _" and nothing else.

Re: [SOLVED] Grub problems

but the partition table was already set for GPT, so that's what fdisk used. I'm not sure how to totally rewrite it.

Re: [SOLVED] Grub problems

I also think that's the problem, because it's hard to install GRUB or even Syslinux like this.

Re: [SOLVED] Grub problems

gdisk is typically able to convert from gpt to msdos partitioning.

So a dos partition is a MBR partition?

No.  But the partitioning scheme used by msdos fs has an MBR.   An MBR is not a partition.

Re: [SOLVED] Grub problems

So, I did as it was pointed to me by WonderWoofy (coolest dog btw) and reformated the entire disk to MBR. Now it's solved. Thank you all for your time.
