install crash

[w5vyc]

I downloaded the version 13 .iso then bought a dvd burner. then burned the dvd and am trying to install.

After an hour of apparently useful install dialog, the install tries to read from / of the ubuntu 12, can't because of security and crashes. I have the partitions for mint, with lots of data installed, but no grub. In the setup I specifically skipped the transfer data section so that there should be no need to read from any of the other operating systems.

Now what?

Did you choose "bring settings and .... something from some other partition". If you did, no wonder if installer crashed.

[w5vyc]

Sorry for the mental lapse. Grub is there but with no changes. ie: no mint.

[w5vyc]

I thought that when I wrote "In the setup I specifically skipped the transfer data section" it would be intrepeted that I did not select any settings to transfer from any other partition.

Anyway, I left both of the check boxes for transferring blank. I think it should not be reading anything from the other operating systems on the hard drive.

I notice that the one response I received for my problem was anotated with: "READ: How To Get Help!"

I have read "how to get help" from the mint forum about 5 times. I have not found out what I did wrong. I have also read the same helpful link for Ubuntu and SUSE a number of times. Would anyone like to share what I did not do and what I should be doing to get help?

Thanks

I have now tried to install mint 12 from a live disk. I even tried using chmod 777 from ubuntu 12 free up security on the ubuntu 12 root drive. I got the same error. The mint installer reports that it needs to read sda6 (ubuntu root) and needs to have it unmounted. Since I am running from the live disk, there is nothing i can mount or unmount.

Please help

I have now tried to install mint 12 from a live disk. I even tried using chmod 777 from ubuntu 12 free up security on the ubuntu 12 root drive. I got the same error. The mint installer reports that it needs to read sda6 (ubuntu root) and needs to have it unmounted. Since I am running from the live disk, there is nothing i can mount or unmount.

A strange problem.
1. Why Ubuntu 12 root drive is mounted during an installation?
2. Is Ubuntu partition encrypted?

If the installation goes well, but grub cannot be installed, you can boot Mint via Ubuntu´s grub running

sudo os-prober
sudo update-grub

If you want install or re-install grub for mint via terminal, it goes like this:

sudo mount /dev/sdxy /mnt # where x=HD and y=partition
sudo grub-install --boot-directory=/mnt/boot /dev/sdx # where x=HD
sudo umount /mnt

If grub cannot be installed, you can try to use LILO or Lecacy grub.

An example about Lecay grub´s installation via chrooting:

sudo blkid # tells the media
sudo mount /dev/sdxy /mnt # where x=HD and y=partition
sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
sudo chroot /mnt

apt-get update
apt-get install grub
update-grub # remember answer Y when asking about menu.lst file
grub-install /dev/sdx # where x=HD
exit

sudo umount /mnt/sys
sudo umount /mnt/proc
sudo umount /mnt/dev
sudo umount /mnt

I found the linux mint 9 live disk. I ran the install from it and now my ubuntu 12 is gone. I'm happy the xp and ubuntu 10 survived.

I find the lack of help unbelievable.

Thanks

Thanks oobetimer. Our post crossed.

The situation is now seriously changed. Ubuntu 12 is gone. I have the Ubuntu 12 live disk in the drive to reinstall it, but I will wait at the drive partition screen to decide what to do.

I will post again as soon as I have an understanding of what is on the drive.

[w5vyc]

It looks like I have all the operating systems on the drive. They are as follows:

sda5 swap
sda6 used to be ubuntu 12 / should not have changed
sda7 used to be ubuntu 12 /home should not have changed
sda8 ubuntu 10 /
sda9 ubuntu 10 /home
sda10 should be mint 9 /
sda11 should be mint 9 /home

I think I should follow your instructions to see if I can get mint 9 to run

Thanks

[w5vyc]

WOW!

os-prober found all the operating systems and update-grub fixed it. The system is now running mint9 and I can use update to get where I wanted to be. I still need to try Ubuntu 12 but is is probably OK. Probably a day or so, but there is sunlight on the horizon.

Thanks more and appologies for the flame.
