Almost all cases of linux hangs I've ever experienced have been from either: 1) mount/unmount 2) insmod/rmmod and they usually last forever. Sometimes prevent proper shutdown, requiring SysRq magic or usually hard power-off...

O_O Well said :) I've heard a rumor that Windows doesn't like GUID partition tables, so I haven't yet installed grub2 on my one machine that still multiboots between operating systems. (That's my one remaining machine with a legal install of Windows.) I confess I'm not interested enough to confirm the rumor, so I continue to wait because there is no incentive for me to make the change.

Although sometimes it seems, with all the complaining some linux users like to do about new software, I must be a wee bit lucky. Been using Grub 2 alpha/beta for years with much success! I've so far enjoyed the configuration more than legacy Grub.

Are you using GUID partition tables? > No, I'm not using GUID right now. But I don't believe this has anything to do with Grub 2 itself and from what I can tell you don't actually use GPT on your dual-boot machine anyway. Though that would take away the main reason to upgrade. Doing a quick DDG search, I see more positive than negative about Windows + GTP. I think we should promote a greater sense of adventure.

Unfortunately it cant log to a file (or at least I have not tried) so sleep statements may help so you read the messages. Copy the above script to a new name and run genkernel as "genkernel --color --linuxrc=/usr/share/genkernel/defaults/linuxrc.uswsusp --initramfs-overlay=/var/lib/genkernel/overlay --lvm --menuconfig all " The overlay is a some extra stuff I wanted in the initramfs for suspend to disk.

I suppose by now everything will "just work" and the various tools will now by default create correctly aligned partitions? Thanks everyone for the comments. I'm using cfdisk, since I find it's the easiest CLI partitioner (fdisk and parted don't offer menus but you need to type commands; I hate that). If you use a GPT partition table, you can use cgdisk and banish the abominations of extended and logical partitions at the same time. OK, I now have the new disk. Unfortunately, it turns out that GPT is not an option, since Grub can't dual boot an UEFI/GPT installed Windows 7 (you can't install Windows on a GPT disk if you don't perform a UEFI install of Windows.) And if Grub can do it, then it's much more difficult to set up compared to a BIOS boot. I surely don't have a clue as to how to do that. So using MS-DOS partition tables in 2012 is still needed. Hooray! PS: And don't get me started on the fact that moving my Gentoo install to the new disk is as simple as "rsync -a -x / /mnt/targetpartition" and only takes 10 minutes, while Windows has to be cloned using partition imaging and modifying partition position offsets so installing it from scratch is actually easier. Sigh...

You need to boot Windows directly via EFI, and linux via an EFI elilo or grub-efi or grub2 loader (elilo.efi/grub.efi/grubx64.efi in the EFI-boot-partition).

[gentoo-user] Rebooted and now I only see the word GRUB
Hi, Tonight I rebooted and only see the text "GRUB" followed by a blinking cursor, never the grub menu. I'm using grub legacy and ~amd64. Of course my recovery options depend on GRUB actually working, so I'm downloading the latest gentoo minimal CD for now so I can hopefully get in and see what's going wrong and fix it, or reinstall grub at least. Anyone run into this problem or have any idea what's causing it? I'm not sure if GRUB 0.xx was updated recently, I don't remember seeing it emerged...

After booting from gentoo minimal livecd, chrooting into my hard drive, re-emerging grub:0 (just in case it has to be built against my latest kernel) and then running grub and doing: root (hd0,0) setup (hd0) it booted normally again. I guess I failed to reinstall grub like this after a portage update at some point... logs show I last instlaled it in May, and have rebooted since then without problem, maybe it was something else. Weird. :)
