[solved] fdisk on a gdisk partition

I've attempted to get away from MBR
and fdisk partioning.

This machine has a BIOS motherboard
ASrock G31M-S with Pentium dual-core
E5300 @ 2.6 GHz. We're moving to
x86_64.

Tried to find everything that has
to do on the GRUB page with BIOS
booting for GUID partioning.

for troubleshooting GRUB section:

Intel BIOS not booting GPT

states that if you decided to use
a GUID partitioning scheme GRUB
may not boot for want of a boot
flag "*" for the /boot partition.
Unfortunately the latest version of
fdisk refuses to execute the "a"
command after gdisk has done its thing.

My gdisk-created partioning scheme is
as follows:

Number  Start      End       Size      Code  Name
1       2048       4095      1M        EF02  BIOS boot partition
2       4096      1052671    512M      8300  Linux filesystem
3       1052672   2101247    512M      8200  Linux swap
4       2101248   976773134  450G      8304  Linux x86-64 root(/)  

When fdisk shows this, it's essentially the same except
"Number" becomes /dev/sda1, /dev/sda2, etc.
My goal is to mark /dev/sda2 as "*" (bootable)
I think I can take the drive and put in a bench
test setting & use another version of fdisk,
but this might break something.

Has anyone taken this approach?

I'm going to mark this a SOLVED the moderators
may remove this thread if they want. The GUID
partiton scheme has become corrupted so
that I cannot answer questions about it

Re: [solved] fdisk on a gdisk partition

What on earth is with your formatting? Why the ballistic approach to linebreaks?

Mod note: not an installation issue, moving to NC.

Text being copied/pasted in nn forums besides here seeking help?

EDIT: Smartphone text? (I don't own one, so I wouldn't know.)

Re: [solved] fdisk on a gdisk partition

have to start this x86_64 install all over
again. Running fdisk from an alien system
(no "w") may have corrupted the partition
layout/ table Have to do that again to
confirm
