Greets, folks . . .
The nifty little WD 500gb SSD has arrived. I stuck it into a little USB adapter device and seem to have succeeded in dd'ing my boot partition. /dev/sda1, onto it. I have employed the appropriate utility to give it a unique ID, and have labeled its first partition as BOOT. (My home partition, on the existing /dev/sda, is labeled HOME, and /etc/fstab are edited to mount LABEL=BOOT as / and LABEL=HOME as /home.)
If things weren't unnecessarily complicated, I could go into the bios and tell it to boot from USB and check the thing before I mounted it permanently. Ah, but . . . There's no nice, normal setting to set boot order in the frigging bios! I can't tell it to just boot from USB and call it a day. Instead, it offers a variety of choices that include booting from a drive that has no operating system at all, so it's not smart or anything like that.
I did update-grub on the existing hard drive installation and it saw and added the SSD install. Here things get weird: sometimes it shows it and sometimes it doesn't. Ubuntu in its wisdom has screwed around with the GRUB2 menu. Initially it didn't't show up at all; after I dicked around with it a little a few days ago I got it to appear. Even then, it isn't a GRUB menu as we know it.
By fiddling around with the bios I can get a menu that contains the SSD -- /dev/ssd1 -- to show up in the GRUB menu, but sometimes not. And even then, if I select the SSD installation, it does fiddle a little with the SSD on the way in, but boots to the /dev/sda1 install.
Now, this is especially problematic because the hard drive boot is, as I mentioned, from /dev/sda1, while /home is /dev/sda3, so just yanking that drive is not among the relatively convenient possibilities.
I'd like to boot from it, of course, for reasons including the ability to run update-grub on it, so that the default boot would be from the SSD when it is happily installed in the system. (After which I'd open a terminal and again run update-grub so that GRUB would get everything in its final configuration, with booting from the hard drive possible in case of SSD failure.)
Any ideas? Prefarably as opposed to guesses?
UEFI?
