| gnarface | been a while since i tried it but i seem to recall something about live images making grub unable to find the right spots on the main drives to configure/install to | 00:01 |
|---|---|---|
| gnarface | i wouldn't want to advise you to do anything that would make things worse | 00:02 |
| leafwiz | yeah.. That sounds about right, I thought I read something like that online just now | 00:02 |
| leafwiz | So I will try with that rescue usb, and see if it will fix my windows | 00:03 |
| leafwiz | :) | 00:03 |
| gnarface | grub-install and update-grub seem a lot smarter when you're running them from inside a booted linux install on a main system drive | 00:03 |
| leafwiz | mm.. yeah. | 00:03 |
| leafwiz | A different question. A GPT drive , can you dd and enlarge the partitions in gparted? | 00:04 |
| gnarface | should be able to, with some caveats | 00:05 |
| leafwiz | I'm going to try move a old drive over to a new drive for a friend. But then I started to wonder about gpt drives | 00:05 |
| leafwiz | I have a feeling tts not straightforward to move those. | 00:06 |
| gnarface | GPT itself isn't a problem for gparted, though i did run into one problem when switching a GPT partition table to MSDOS type when windows had formerly been on the drive, in which gparted failed to zero the entire partition table and there were false-positives on GPT detection with other tools. not sure that has been fixed or not but the solution i used was to just zero the first few megabytes of the drive and reinstall | 00:07 |
| leafwiz | Okay, good. This is also windows, so my plan was first to try the drive manager, and see if that wanted to expand it | 00:08 |
| gnarface | but gparted doesn't carry its own filesystem support, so resizing filesystems means you need to have the tool sets for those filesystems also installed (but gparted has a menu that can tell you which ones you have installed easily) | 00:08 |
| leafwiz | but if that was nogo then I wanted to try gparted | 00:08 |
| leafwiz | But I now gpt stores a table in the end of the partition | 00:09 |
| gnarface | and note that not all filesystems can be resized while mounted | 00:09 |
| gnarface | if you're talking about moving a drive, the bigger issue may be if you're moving from BIOS to UEFI | 00:09 |
| leafwiz | mm.. yeah. I'll have to see what he has. and yeah. if the drive is larger than 2TB | 00:10 |
| leafwiz | I have been reading up on gdisk. It is able to convert mbr to gpt | 00:11 |
| leafwiz | without dataloss | 00:11 |
| gnarface | yea the only problem i've had with that was going back in the other direction from gpt to mbr | 00:11 |
| leafwiz | mm.. yeah, that is a bit different he said | 00:12 |
| leafwiz | the writer | 00:12 |
| gnarface | and it was specifically related to also having had windows7 on the drive at the same time | 00:12 |
| leafwiz | bit harder | 00:12 |
| gnarface | basically windows did something "special" to some internal gpt config that gparted wasn't smart enough to remove | 00:12 |
| gnarface | but that was a couple years ago now so it may have been fixed like i said | 00:13 |
| leafwiz | Yeah, but I think gdisk will work well from mbr to gpt, but then I wonder if the windows bootloader will accept a gpt parition. So I prob need to use the rescue disk to have it make a new bootloader | 00:16 |
| leafwiz | But thanks for the info. Take care! :) | 00:19 |
| rwp | I am just going to note that the Debian wiki page has some useful information on UEFI rescue https://wiki.debian.org/GrubEFIReinstall | 00:27 |
