Boot flag

Hello all

I've looked on a command to set the bootable flag on Linux. I've found out that fdisk would TOGGLE the boot flag only. What about if I liked to set a partition as bootable?? Specially that I've had some issues with G-parted not running so that I could make my partition bootable?

Thanks

Re: Boot flag

Hi neru,

What a problem? If it cleared - TOGGLE it, and it will set. If it is already set - just don't touch it. Really, I'm not in my Linux now, and have no any terminal in my smartphone, sorry if I can't understand your problem.

Hope, it helps you:

They wrote that Linux bootloader not look at boot flag at all.

Re: Boot flag

Open terminal,su,password:root

Type in terminal:

[c]gparted[/c]

Hit enter key

Post the output/errors if gparted doesn't start.

Re: Boot flag

Probably the Language error again. Try running it as LANG=C gparted from the terminal as root and see if that helps.

Re: Boot flag

if gparted is broken, try parted:

[c]$ parted -l[/c]

lists partition layout on all devices

and to set the boot flag on:

[c]# parted /dev/sda1 set 1 boot on[/c]

for the first partition on /dev/sda1

[c]# parted /dev/hda1 set 2 boot on[/c]

for the second partition on /dev/hda1

Re: Boot flag

Thanks for your help and advices.

In fact there might be some kind of hardware problems since I've encountered many errors messages like "no bootable partition" before that were resolved...even if it isn't obvious for you, I'm quite sure that it's specific to Slitaz 4 Core that I'm running and my hard disk.

Once I run G-Parted, it goes a little for a devices scan then shutdown.

Also run from terminal...

While I don't have any problems with Slitaz 3 (but I'm encountering Wifi problems )
