    hang on ``Verifying DMI Pool Data`` at boot

    I was running Ubuntu with an uptime for some two weeks or so. After downloading Black Mesa Source today, I attempted to boot into Windows 7 to install the recently released mod but I got an error message before Grub2 loaded. The message read, “BOOTMGR is missing.” I then booted my Ubuntu Live disc and Googled the error message. I can’t recall exactly what it was that nudged me towards the conclusion that it was my two mass storage USB sticks plugged into my PC. I have my boot priority in my BIOS set to USB-HDD, CD Drive and then hard disk. My BIOS was probably looking for an O/S on those two storage USB sticks and it couldn’t find any. I removed my USB sticks which eliminated that error message. However, I then encountered different unusual behaviour. Now it hangs after, “Verifying DMI Pool Data.....” Google tells me that the source of problems similar to mine involve hardware and not software. Since I don't even get to Grub2 boot loader, it can`t be a problem with Ubuntu or Windows. As per advice I found on Google, I tried reverting to factory default settings in the BIOS. This yielded “Update Success” after ``Verifying DMI Pool Data,`` but it still hangs. Also, I think my hard disk isn't the problem. My Ubuntu Live environment detects all the hard drives. I can see the contents of all my partitions, so I think I can safely rule out that it`s a faulty hard disk. What else could it be?

    Try booting into a live cd and running memtest86 or run "sudo dmidecode --type memory" from a terminal I had an identical problem to that plus when I could boot to a livecd it would say "dmi-table-broken-stop" in the hostname turned out to be bad ram "1Gb of PNY DDR2 Ram"

    Does the demidecode command supposed to indicate whether I have bad memory? I also have Memtest86 running right now.

    Code:
    ubuntu@ubuntu:~$ sudo dmidecode --type memory
    # dmidecode 2.11
    SMBIOS 2.4 present.

    Re: hang on ``Verifying DMI Pool Data`` at boot

    My problem is that I can't get to my Grub2 bootloader because it hangs at DMI Pool. The work around I figured out is to use a Super Grub2 LiveCD to detect the Grub2 configuration file on my home directory which resides on /dev/sda7. However I'm still in need of a permanent solution because I don't want to use Super Grub every time I want to boot an O/S.

    Re: hang on ``Verifying DMI Pool Data`` at boot

    From your last post it seems that the BIOS does not actually hang, but is probably waiting for something (which is different of 'hang' state) or has done its job but the subsequent process (loading OS maybe?) is stuck or unresponsive.

    What if you boot with the hard disk disconnected? Does it still hang on the same screen or return some "no boot device found" type error?

    Some BIOS programs (even on some modern boards) are so stupid that they don't even try to boot from other available media if you have not included it in its boot sequence and in correct order. So make sure that the hard disk is listed in BIOS boot sequence and is on top in its category.

    If it is already ok, then maybe there is some problem with MBR (as the error message in your original post indicated). To figure that out and possibly correct it, boot with live cd, install boot-repair, run it and post back the pastebin link it creates (or the contents of "Result" file it created in root's home).

    Thanks, varunendra. I ended up using the 'Recommended repair' feature in the Boot Repair app you suggested. I should have reported back here sooner, but I got carried away with other things. Thanks again. =D
