GRUB2/dual booting questions?Post here please.

[Cell]

First I want to say GRUB2 is not anything like the old GRUB! If there's no other OS, grub will be hidden by default. Hold the shift key down to make it appear.

O.K. thats out in the open.

I personally did this with XP.I've read it works with Win7 also.

Now...say you have xp,or even win7 installed,and want to dual boot.You install your brand new U.E 2.4,and reboot...Where the heck did my M$ partition go? (Take note this doesn't happen often,but it can) Relax...Its O.K. Heres four non geeky steps If you don't have an M$ cd to recover your M$ mbr...well 3 non geeky steps,but hey Its easy.

1) Boot with the U.E live dvd or USB

2) go to the web and download the ms-sys deb(64bitor32bit depending what live dvd your using.(if you enable the repo's on the live disk you can get it from synaptics too.)

3)in a terminal...this is the geeky one.

Code: Select all

ms-sys --mbr /dev/xxX

xxx is what ever drive you M$ system is installed on.You can use the partition editor to figure this out.

4) Reboot.

You should see the Grub screen with your M$ OS in it.That wasn't so hard now...was it?

"Hey Cell it didn't work" your thinking (maybe yelling)...well you might have to update grub.The non geeky way to do it is to boot into recovery...remember the "hold shift" I mentioned above? When your into recovery scroll down to update GRUB,and press enter.

Keep in mind that GRUB2 is still evolving.In the past I always said "don't update.If it ain't broke.Don't fix it" Well now I do recommend updating...just be wary of what is updating on your machine.


I would like to thank Ranch Hand a.k.a. Widget for his hard work testing GRUB2.

Grub2 is very slow - at least on my PC - it takes nearly 55 sec. from the first line with "GRUB loading" until I actually can choose what to boot and my HD's working like they were paid for it

I have added a new 160Gb sATA HD and installed 2.4 on it with a 20Gb partition as / and with a 40Gb /Home and reused the swap on the other disk, witch contain Ultimate Edition 2.0 - 2.1 - 2.3 along with WinXP pro (don't use it any more) Mint7, Xubuntu 9.04 - the last two only for test-purposes, don't like either
With the "old GRUB" it took only a few sec. before I could choose and with only one dist less than now

I wonder if that is because it's new and beta and in time will be faster, or it's something I will have to live with

It should be fixed in future releases.I boot with four hard drives(one is a usb),and it pretty quick on my system.

There is a bug files for this too.Ill ask Ranch Hand (my neighborhood grub expert) if he knows anything about it.

I will greatly appreciate if he know a fix for it, because this is a bit of a pain
(I don't know if that is what's going on, but to me it's like it don't remember anything from last boot and search all the drives for OS'es on every boot) have to look for where it's suppose to store these informations

You can roll back to the legacy grub.*I think.

[Hawks-SOAD]

so there is no editing the grub menu list no more?

Nope.

[Admin-Amir]

One more thing,
there is no more Editing for the x.org.

[Moebius]

After installation of Ultimate Edition 2.4, Grub2 automatically detected Windows 7 and OSX, and setup everything perfectly. So far so good with Grub2 here.

Cheers.

you edit another file ( grub.cfg) & then run the Grub update command.

similar thing for the xorg.file.

it's gonna take time to get use to this method of doing things.
supposed to be more flexible - usable - method of doing things.
