Re: Re: Building computer



Hi Catherine Gramze,

Recently one of my friend's brother bought a Lenova laptop. My friend asked me to install Ubuntu in that laptop but that machine was not detecting Ubuntu and directly booting into Windows 8. Then after bit of struggle, we went into the bios and changed the boot mode from 'UEFI' mode to 'Legacy' mode. Since we were installing by pen drive, we changed the boot order also.

After the above steps, it detected Ubuntu and we finally installed Ubuntu along with Windows (as dual boot). The problem starts now. We were not able to boot windows from the Ubuntu grub menu boot entry. If we want to boot Windows 8, we need to change back the boot entry to UEFI mode in the bios and then only Windows boots from Windows boot manager.

The reason behind this is Windows 8 is been made to boot only in UEFI mode and hence the OEM vendors (like Lenova) are configuring their machines accordingly. They don't mind/care about other free software OS.

Just before this instance, I bought a laptop prebuild with Ubuntu (DELL vostro 2420). It doesn't had these circus as it was shipped with Ubuntu.

I thought of sharing this details with you and our fellow community. The link 'http://www.fsf.org/search?SearchableText=secure+boot' shared by Bob gives you some insight on this restricted booting.

It looks like you ran into the MS Window 8 Restricted Boot problem.

So, I am looking for recommendations on hardware, particularly
motherboards, known to play nicely with Debian and boot
consistently. Building my own system is not new to me, but something
I have not done for 10 years or so, so the appropriate BIOS settings
on the new EFI and UEFI mobos are unknown to me. All advice is
solicited.
Check the dates on these older postings (time flies and the best
hardware moves along) but here are two references:
