My regular Thinkpad a Lenovo SL410 has a large HD so I keep 4 Linuxes installed on it. You can see this in my Signature.
Today I went into Kubuntu 10.04 LTS install which I don't do normally and had 393 Updates waiting for me.
So, I bit the bullet and Updated the packages. One of the Packages was Grub PC but as I use the Sabayon Grub I wasn't expecting Kubuntu to Install it's Grub on the MBR. Well it did........
Next step I booted the Sabayon Live 5.5 CD and used the Handy option (thank You) to reinstall the Grub.
Normally I would have done so from the CLI.. but I wanted to see the CD work for me.
When I rebooted after the Sabayon DVD had finished reinstalling GRUB I was faced with the Usual Ubuntu 10 additional GRUB entries..what an annoyance.
Next I logged into the Sabayon Desktop as user Sqlpython hit Alt-F2 and typed kdesu kwrite
I was asked for my root passwork BUT it was not accepted..
I typed and retyped carefully but somehow it had changed.. Come to find out it had not changed but was BLANK
In a console I typed su and when Asked for a password: I simply hit the enter key and I was root..
So I ran the command passwd and reestablished my Original root password...
Wereby I ran
and edited /boot/grub/grub.cfg to clean up the Grub Menu..
Has anyone ever encountered this behavior..?
Not so much another OS overwriting the MBR with another Grub but
...the Blanking of root password after using the Sabayon CD to reinstall Grub...?
Criticism accepted for Solutions that work. ;^)
