virgo89 Posted January 12, 2009 Share Posted January 12, 2009 hello, I have one hard drive with 4 partitions. The first one and last one are by Acer, and dont show in My Computer. I made two partitions out of my C:/ One for Xp and one for Ubuntu. The installation of Ubuntu 8.10 went fine, except when I restarted my computer I did not get a choice of which OS I wanted to boot. Instead it went straight to Xp. With a little bit of researching, I went into my LIVECD and opened up terminal; sudo grub find /boot/grub/stage1 After that I get "Error 15: File not found" Can someone help?

Lechio Posted January 12, 2009 Share Posted January 12, 2009 Did you installed GRUB? Please open a console and copy>paste the output of the command: sudo fdisk -l so we can see how your disk is partitioned. Also the contents of the GRUB configuration file "/boot/grub/menu.lst" from your ubuntu install (not the one from the LiveCD) would be nice.

virgo89 Posted January 13, 2009 Author Share Posted January 13, 2009 Sorry to change the subject, but I got tired with installing linux on partitions. So what I did was format the whole disk and install Ubuntu 8.10 on it. The installation went flawlessly but when I rebooted I got "Error 21". I tried getting the /boot/grub/menu.lst for you guys but there is no "grub" folder inside "boot". Link to comment Share on other sites More sharing options...
Lechio Posted January 13, 2009 Share Posted January 13, 2009 I tried getting the /boot/grub/menu.lst for you guys but there is no "grub" folder inside "boot". Sure there is, if GRUB is installed. Error 21 in GRUB means the selected disk doesn't exist. Boot with the Ubuntu LiveCD, open a terminal and do the following: cd / sudo mkdir ubuntu sudo mount /dev/sda1 ubuntu sudo chroot ubuntu sudo grub-install --no-floppy /dev/sda sudo reboot This will reinstall GRUB on /dev/sda.

virgo89 Posted January 13, 2009 Author Share Posted January 13, 2009 ^ Thanks I will give that a try. I was wondering, does it matter if the /dev/sda harddrive has no jumper pin on it? On the Maxtor harddrive it says "No Jumper = Slave". I think this might be the issue. However if I place the jumper so that the HD is MASTER my computer can no longer see the DVD drive, and therefore cannot boot from LIVECD. Any comments on that?

Lechio Posted January 13, 2009 Share Posted January 13, 2009 If it's an IDE device, one device has to be set to master and the other one to slave. Change the jumper on the DVD drive too, and put the master device always at the end of the cable. The jumper on the drive can also be set to "cable select". If you motherboard has two channels, put your DVD drive on one and the HDD on the other. Link to comment Share on other sites More sharing options...
virgo89 Posted January 13, 2009 Author Share Posted January 13, 2009 Boot with the Ubuntu LiveCD, open a terminal and do the following: cd / sudo mkdir ubuntu sudo mount /dev/sda1 ubuntu sudo chroot ubuntu sudo grub-install --no-floppy /dev/sda sudo reboot Okay so I placed the jumper so the IDE drive is now "Cable Select". That made my DVD drive appear, so I booted using the LiveCD. In the terminal I put what you told me except at the line; sudo grub-install --no-floppy /dev/s I got /dev/sda: Not found or not a block device. :cry: If it's an IDE device, one device has to be set to master and the other one to slave. Change the jumper on the DVD drive too, and put the master device always at the end of the cable. The jumper on the drive can also be set to "cable select".If you motherboard has two channels, put your DVD drive on one and the HDD on the other. If the jumper on the drive is set to "Cable Select" what should the DVD drive be set to? Link to comment Share on other sites More sharing options...

But wait... Did the partition mount without any error before you tried to install GRUB...? If the jumper on the drive is set to "Cable Select" what should the DVD drive be set to? One set to master and another one set to slave is the ideal configuration. But if you wish to have "cable select", both devices should be on "cable select". "cable select" means that the device at the end of the cable is master and the other one is slave. Link to comment Share on other sites More sharing options...

Lechio Posted January 13, 2009 Share Posted January 13, 2009 Good news, the device /dev/sda is still there. Just don't understand why GRUB couldn't map it before... Reinstall of Ubuntu would be an option for you? Link to comment Share on other sites More sharing options...
virgo89 Posted January 14, 2009 Author Share Posted January 14, 2009 Well, I installed ubuntu on a 10gb Xbox HD inside a USB Enclosure, and it worked fine. Must be something wrong with the Maxtor 120gb drive and DVD drive. Link to comment Share on other sites More sharing options...
