grub loading error 18

Postby Jjude on Mon Oct 26, 2009 3:26 pm

not sure what happened on my netbook, been using mint 7 on it since it came out. Ive had till now not one problem with it. Im still only a newby to linux, and only need an OS to surf and check mails.

netbook started fine this morning, and whilst opening hotmail from amsn, i got an error ( of which i cant recall what it said sorry) so restarted netbook, and since ive had one message as its loading saying, grub loading please wait, error 17, restarted again and get same message with error 18, should i just reinstall mint 7, theres nothing on netbook to save.

Depends if you feel like trying to repair grub or not, if there's nothing major lost and you don't have any special modifications that would take awhile to redo, then a reinstall is probably the least painful move here. JMHO

Can you get into the bios setup fine, and check that things look OK there as far as bios identifing hardware.Maybe resetting the bios to default settings. Make sure it's definitely capable to boot from the usb port, maybe a bios seeting is out of wack there.

Also reflashing the bios might be in order.

Maybe a more experienced user has more or better suggestions than I've come up with.

as far as i can see, everything in bios looks fine. as for flashing, im not expert enough to even try.

Thanks for your suggestions so far, they are much appreciated. If id do solve this problem one way or another, Ill let you know.

Thanks again.

also.... the attempt to mount a file system with type ext3 in sc12 (o,0,0,) partition #1 (sda) at / failed
you may resume partitioniing from menu, i can go back ( get same result) or continue and get the prepare disk space. using entire disk space gets me to the above error message, specifying partitions confuses me.

Does the live usb Mint session work, in other words can you run Mint off the usb like a live-cd? If so you should be able to run the installer and yes use grub even with one Mint install, make sure to install the bootloader to the MBR of the drive.

If you can't get a live session to work from the usb pendrive then we need to address that first.

Hi Maddog, yes I can run mint live from usb, Ive tried the installer, but install only gets to partition bit then no matter what i try it does round in a loop. i keep getting input/output error and im not sure if its just a small user error thats causing me the problems.

Enter into the bios at bootup and see if the bios even sees the HD first.

Have you tried from the live usb running the gparted (partition manager) app and setting up the partitions in that app first then attempt the install.
