Grub not working on dual boot of Ubuntu 12.04 LTS/11.10

[Olivia]

I’ve never dual booted before so I’ve never had to even fear myself with grub, I utilized the 11.10 exist CD to put a parcel for 11.10 alongside my 11.04 and after that redesigned the 11.10 boot utilizing systems plot in the 12.04 sub forum to update to 12.04, works terrific so far so exceptional. at what time I first boot I hold the essential grub screen, in the event that I select 12.04 no situation it boots, if in any case I select 11.04 it appears to delay at a further grub arouse and any alterations made to the 11.04 grub.conf will just tackle this second grub organize, it could have instated grub inside grub by oversight, any advice on the best way to sort this out?

Highlight whole document and click on # in edit panel (code tags) to make it more straightforward to peruse. Or You are able to produce the tags first by pressing the # symbol in the New Reply Edit toolbar and after that glue the substance amidst the created . V60 has enhanced organizing and needs code tags to make it intelligible. New Version is a zip file that you need to concentrate to get .sh to run.

Grub is working fine but Ubuntu begins to stack you might as well get a Plymouth splash screen emulated by the login screen. Conceivably Pylmouth is having trouble advancing. Have you been altering the desktop in any way?

I messed my Plymouth splash. I hold a representation as a base level for the Grub menu and when I pick 11.04 the Grub underpinning level visualization remains an extended time and I make a point not to consistently see the Plymouth screen. Altogether as in your case this tries not to happen assuming that I select the alternate OS, which is 11.10.

You might as well likewise know that the final Ubuntu to be installed will put its particular Grub in the MBR that is why updates to the 11.04 Grub try not to work. You will in addition spot that a kernel update in 12.10 will in addition update the 12.10 grub. I utilize grub-customiser. Whenever grub moves toward getting altered by the install of an additional Ubuntu or a portion update on another Ubuntu, I stack 11.04 and run Grub Customizer and get to recovery the 11.04 grub into the MBR. That fixes things for some time.

I think grub is installed to the MBR of /dev/sda and moreover to the boot division os /dev/sd(n). Altering that could be more straightforward with this grub CDS, startup supervisor, and so on. Be that as it may toward the finale, what it will do if utilize dd to zero the MBR and the bootsector and reinstall grub to one of them, and conceivably reproduce a segment table (which is not compulsory as most BIOS know where to look at the outset of disks).

One thing I like: Google for "Creating 1MB GRUB Partition". It cannot be overwritten unless mounted. You could probably computerized-unmount it unfailingly an OS boots. But also you are able to mount it when you need to update-grub.

[Vitel]

Symptoms are that the 12.04 introduce decently specified /dev/sda and the 11.04 somehow specified /dev/sda1 (1 or whatever parcel 11.04 is in). Grub might as well just be put on /dev/sda or /dev/sdb, and never within a partition unless you know an entire parcel more about grub than I do.

[DakshaMira]

In the event that you would be able to get the 11.04 up, attempt

sudo upgrade-grub
sudo grub-establish /dev/sda

that method updates to the 11.04 should to get to grub on /dev/sda. Make a point not to detail /dev/sda1 or whatever possible number when the "a".

[Ticod]

I don´t have any dual boot situations. I have /dev/sda1 windows 8 and /dev/sdb1 windows 7 and ubuntu 12.04. Grub menu works fine, which I prefer to turn on the system.

[VazV]

I think Ubuntu 11.04 was their first and was during that timeframe) the just OS, so I gather might as well have installed to /dev/sda, I guarantee you I try not to know more of grub than you gentlemen so relish the advice, I will attempt your orders, in addition much appreciated admin for moving the string I was 50:50 concerning in case to put it here in the ahead of all comers.

[Nimos]

There is no requiring removing grub from a PBR as it could never be utilized by grub unless you totally would like to boot that way. The space is just utilized by Windows & Lilo for booting.

[phantom309]

I have a dual boot, dual disk system. Windows 7 one drive and Ubuntu 12.04 on another. I manualy booted through my Bios to get to Ubuntu after update. Then in Terminal, I used;

$ sudo add-get-repository ppa:yannubuntu/boot-repair && sudo apt-get update

Then

$ sudo apt-get install -y boot-repair && boot-repair

A boot repair pain will pop up and use "Recommended repair" button
(repairs most frequent problems)

Everything works fine...
