Hi,

I don't exactly when this started, but I hadn't booted my mythbuntu box for a while. When I boot it now, it hangs after grub at 'Starting Up...'.

I was running 9.10 64bit, with 4GB Ram installed on an AMD64 3700+ ASUS A8N5X mobo.

How can I resolve this? Can I modify boot options by hitting the Esc key before grub? What options should I use?

I made no changes myself, it just happened on the next reboot. I hope that I won't have to burn a livecd. I only say that because the only machine that I have with a decent burner is my 9.10 box. But if I must... I must.

Thanks in advance for your help

more info reqd

dmesg

try booting in recovery mode?

grub ->
press e to edit

remove the options quiet, vga .. in kernel line for more info

Hi,

Thanks for responding. Booting the current kernel in recovery mode, the only message that raises my eyebrows is that 'No AGP bridge found... aperture pointing to e820 ram. ingnoring. your bios doesn't leave a aperture memory hole. please enable the iommu option in the bios setup.

No vga in kernel line.

Took out 'quiet' but doesn't display any additional information.

Don't know where to run dmesg.

I will try to remove some of the memory to see if that allows it to boot.

Hi,

Update. BIOS memtest works. memtest86+ reboots.

I'm going to remove memory and see if the system boots.

Found the problem. Sorry for the trouble. Somehow a bios setting was changed. I think my battery is no good. Once bios setting changed back to previous setting, I boot fine.

Thanks amani. You helped a lot.

About the messages:

add the option iommu=noaperture in the kernel line if you have no such thing in the bios
