12.04 installed to SSD and it won't boot

[tderanger]

Hi Guys,

first of all, happy, happy X-Mas to all of you! :cool:

Ok, I've installed Kubuntu 12.10 to my sda (256GB Samsung 830 SSD). 8GB Ram, i5 Processor. (There's no other hd.) To make things easier, I just let it completely use sda.
The entire install works fine, until I get past the final reboot message.

If I use hd boot, I get:
"Loading OS...
Read Error"

If I choose boot from 'cd' (dvd) and let it timeout, it finally falls back to hd and only then propery boots up Kubuntu.


(What I've allready tried: dd the MBR with zeros, reinstall. dd the entire SSD with zeros, reinstall. SATA Smart erease, reinstall. Nothing helped yet.)

Is that a 12.10 bug?
Any workaround?

Heeeeeeeeeeeeeeeeeeeeeeeeeeeeeeelp!!! I don't want to reinstall Win.

I just did this:

"apt-get remove --purge grub-pc grub-common
apt-get install grub-pc
grub-mkconfig
update-grub
grub-install /dev/sda"

But to absolutely no avail. >

Sounds like possibly a bad disc image from the CD burn. I've had this happen to me a few times. Did you check the MD5SUM (hash) of your kubuntu download?

Suggests to me that the image is correct (since it boots) but the bios is not booting the correct disk :S

Is your system uefi based or bios based?

If it is uefi based then make sure you install the right version of grub.

AFAIK (downing 12.10 64 dvd again + 12.04 64 dvd), it's BIOS based.
The system is an aprx 1,5 years old prebuilt Gigabyte mb system.

I'll check once it's finshed dling.

it sounds like it is installing right but the BIOS is having trouble deciding what to boot (cd,HD,SSD,) check the boot order in the BIOS and play around with the settings changing the boot device order around and see if you can get it to boot the correct drive first ,,,,,thare may be an option for SSD , I dont know for sure as I dont have anything that new :-P

Hi,

I checked whether it's still a Bios machine. Yes.
I downed 10.4 64bit, checked md5sum and text-installed it onto sda (grub2 to sda). Still no boot via hd mode.
(Between all those Kubuntu tests I shortly/temporaryly installed win7 back. Booted in hd mode right away.)

I can choose first hd, scnd hd, cd (dvd), network, external usb as temp (F12) or fixed boot device. There's no dedicated ssd device. It shows the correct device (Samsung ssd 830) once choosen (first hd), however. All boot options (besides cd-timeout-hd) fail.

Cheers...

P.S.: The system is still in AHCI mode from win. Is that a prob? Do I have to fall back to IDE?

[tderanger]

Hi,

falling back to ide solved my boot prob.

Weired to know, AHCI and USB 3.0 won`t work.

Thanks for anyone here trying to help noobs as me out
