| grantbow | q: random friend gave me an HP Pavilion dv6 aka qg291ua laptop that fails to boot windows 7. My usb 12.04 grub boot medium boots to a black screen with a blinking cursor. I think I need a magic kernel parameter to make it boot. any suggestions? | 02:48 |
|---|---|---|
| akk | Do you know if it's actually booting from the USB (and then failing), or not even seeing the grub boot at all? | 02:55 |
| akk | I'm wondering if it might be a bios boot setting issue rather than a problem booting grub. | 02:55 |
| grantbow | it's booting grub2 and when I loopback mount the iso it seems to load the kernel and sit there | 02:55 |
| akk | So much for that idea. | 02:55 |

| darthrobot | Title: [Booting ISOs from GRUB 2] | 02:56 |
| grantbow | it works on many machines but not all | 02:56 |
| nhaines | grantbow: my laptop is a dv6 and boots with no modifications. | 02:56 |
| grantbow | I was caught without my other machine and other medium to try booting from | 02:56 |
| akk | Ah, this isn't a normal single live usb, it's a grub-with-isos thing? | 02:56 |
| grantbow | nhaines: interesting | 02:57 |
| grantbow | akk: yes | 02:57 |
| akk | I have one of those too, but I've sometimes seen it fail on machines where a normal live usb will work. | 02:57 |
| nhaines | I would try a DVD. It's the computer or it's the install media. | 02:57 |
| akk | I don't understand why (I confess I don't totally grok how the grub-to-iso transition happens). | 02:57 |
| akk | (I don't think anyone else groks it either -- at least, if anyone does they're not writing public explanations :) | 02:58 |
| grantbow | it doesn't like the 12.10 dvd | 02:58 |
| grantbow | I hate the bios dance. booting a machine shouldn't be so hard. | 03:01 |
| akk | We'll all come to love bios after we have to "up"grade to secureboot UEFI machines. :( | 03:02 |
| nhaines | UEFI without secureboot is awfully nice though. | 03:02 |
| grantbow | aha! It doesn't auto-detect cd and dvd well. Manually telling it to go to disc is working! | 03:03 |
| nhaines | Last client machine I built had a pretty mouse-driven GUI. I had to keep shoeing her 6yo away from it. | 03:03 |
| akk | The older EFI on macs was a major pain with ubuntu. | 03:03 |
| grantbow | or, tries to work, darn it, same black screen and blinking cursor | 03:03 |
| grantbow | nothing on ctrl-alt-F1 vt | 03:04 |
| grantbow | I think this is a qvc model | 03:12 |
| grantbow | after long timeouts it finally booted. Not sure if there is a hardware problem involved or not yet. | 03:29 |
| grantbow | at least I can copy files off now! hurray! | 03:29 |
| akk | It's a start! Yay. | 03:29 |
| akk | Wonder what the timeout was doing/waiting for? | 03:29 |
| grantbow | udevd [*]: timeout: killing '/sbin/blkid -o udev -p /dev/sda?' [*] | 03:31 |
| grantbow | with numbers for the *'s and ? | 03:31 |
| grantbow | the trouble will now be talking my friend through booting from CD with the right timing on the esc key and choosing the CD. | 03:34 |
| grantbow | I can rest easier knowing at least it can be done | 03:35 |
| grantbow | toggling wifi made it scan to connect, that's a good sign | 03:36 |
| akk | Yes, that's often the hardest part getting laptops to work. | 03:36 |
| akk | Hope it's not broadcom. | 03:37 |
| grantbow | bcm4313 but it worked out of the box | 03:40 |
| grantbow | though it is throwing qos stuff to the console vt | 03:41 |
| nhaines | PLOT TWIST: installing the proprietary driver kills wireless support. | 04:18 |
| nhaines | Just finished work on my new Ubuntu business cards. If I get good feedback I'll print them in time for SCALE. :) | 09:12 |
