I am getting error messages while trying to install ubuntu 12.04 on my desktop (Intel Pentium D). The error messages are:

*checking battery state...

I was able to install on another PC (Intel Atom) but not on this PC (Intel Pentium D), Can any one help me in successful installation? Thanks!


Check out this Squashfs Errors community help page. This might help you to resolve the issue.

Here is the gist of the fix provided.

Temporary Workarounds

Some users have reported that adding the ide=nodma or acpi=off allowed them to work around this issue (which proved to be bad memory modules). You might want to give that a try

Successful boot was achieved by adding "all_generic_ide" to the grub boot line for the live CD.

You can add those lines to the grub entry, either in the grub.conf file or either entering letter 'e' on the grub menu and after editing Control+x to boot:

Add to the grub line:

all_generic_ide pci=nommconf

Add to the kernel line:

ide=nodma acpi=off

  • Thanks for replying. After trying to install on SATA HD and ATA HD with no result, it shows the issue is with Pentium D processor and its mother board 102 series which is not supporting Ubuntu installation. Even the side by side with windows never worked, its been years now, failed to install on this PC. – VRU Dec 15 '12 at 10:05
