comment Why does BIOS needs to load first stage boot loader from MBR, but this is not the case with UEFI?
@mikeserv, that's not what he said ( or at least not the part I quoted ).. the part I quoted says that the whole partition is the boot loader.. that's not true... it's a filesystem that holds various files, one of which is a bootloader ( and there can be multiple ones installed, which was always a problem with bios ).

"UEFI uses an entire partition as its first stage boot loader" is a bit incorrect. It uses a file that just needs to be stored in a partition that it can read, and the only filesystem type it is required to be able to read is FAT.

comment RAIDing with LVM vs MDRAID - pros and cons?
You are in fact, getting that error due to the version of lvm in wheezy being extremely old and buggy; it works just fine for me here on Ubuntu 14.04 with lvm version 2.02.98 ( I believe jessie is at least that new ). Secondly, the command you showed failing is a resize -- reshape is something entirely different. Reshape means changing from raid1 to raid5, or from a 3 disk raid5 to a 4 disk raid5. That is still unsupported, but simply changing the size works fine.

LVM has always supported raid1 and raid0. It was more recently that they dropped their own implementation and instead internally use md's raid personality code, opening up the other raid levels.

comment Ethernet only works when PC booted with cable plugged in
Sounds like a busted router then. You might fire up wireshark and see if any packets are being received.

Retry the DHCP request? Try using a static IP address?

comment Boot process - Dev sdX name changes
Odd. It should be hd0, since the bios always makes whichever drive it loaded grub from hd0. Like I said before though, if the drive where /boot is changes to another number, then grub won't be able to find grub.cfg in the first place, so it won't make it to the search command.

comment Boot process - Dev sdX name changes
I do so all the time and it works just fine, of course, because the line right before the search sets the root to point to the correct place. Thus following the set with a search to re-set the root to the same place is redundant.

comment Boot process - Dev sdX name changes
You dont't need it. I still can't figure out why they bother putting that in there since grub wouldn't be able to find /boot/grub/grub.cfg in order to even execute that search command if it didn't already know where /boot was.

comment unbootable usb stick “Non-system disk or disk error”
Right... LILO doesn't care about the boot flag.. but some bioses do... so if you didn't have it set prior to installing extlinux, and installing extlinux did set it, then that is what fixed it.

Are you quite sure that you had a partition flagged as bootable before? If you install lilo to the MBR after, then extlinux is unused.

Make sure you mark a partition as active/boot as some stupid biosen refuse to load an MBR otherwise.

comment How to recover a partition recreated with gparted
What happened is you formatted your partition. You weren't supposed to do that.

Yep; if you don't backup your data, then sooner or later, you will lose it.

comment Smarter filetransfers than rsync?
The whole point of rsync is that it finds only the parts that have changed and sends only them.

comment Multiple passes of wiping disk with `dd`
@NoTime, since we are talking about shredding the whole disk/partition rather than a file, none of that applies.

comment Multiple passes of wiping disk with `dd`
@NoTime, shred overwrites the target with random data multiple times.. i.e. exactly what you are trying to do.
