[gentoo-user] Change Partition Type

[gentoo-user] Change Partition Type

[Michael Crute]

I have a laptop and when I initially setup the partitions I
anticipated that I would install Windoze along side of Linux for
gaming purposes, I now realize that this is never going to happen and
would like to change the partition type from NTFS to Linux Native. Is
it possible to do this without hurting the other partitions on the
disk? I really can't afford to re-format/re-install the whole machine
right now.

The partition structure looks like this:
hda1 -> NTFS (unformatted, want to convert over to Linux Native + ext3)
hda2 -> Swap
hda3 -> Linux Native (formatted ext3 with Gentoo installed)

simple.

mkft.etx3 /dev/hda1

done.

it won;t affect anything. 

unless you want to have evrything as 1 big partition.

eg: had1 - linux
hda2 - swap

then u have more work .

No problem!

Just reformat /dev/hda1.  Doing this will not touch the other
partitions.  Of course, if you are booting off of /dev/hda1 now, this is
problematic...

See the man page for mkfs for more info.  Something like:

	mkfs -t ext2 -m1 /dev/hda1

In addition to what others already suggested, it also would make sense to 
actually change the partition type in the partition table:
	fdisk /dev/hda
then press "t" and type partition number (1 in your case), then 83 (Linux 
Native) when asked for partition type.

Right, this is exactly what I want to do but can I do it without
seriously screwing up the disk? i.e. can I change the partition type
without screwing up the existing partitions?

Yes, you can change the partition type of /dev/hda1, it will not affect other 
partitions on /dev/hda. Just set it to Linux Native using fdisk and then mkfs 
it to ext3.

Yes, because that's all you are doing, changing the type flag for one
partition. You aren't touching the filesystems, or the information for
the other partitions, at all.

As long as you only change and format the NTFS partition you should be 
fine (you don't have any data on there that you need that isn't backed 
up, right?)

Yes. Use fdisk to do so. Changing the part. types won't hurt
the other partitions.

Perfect! Thats what I needed to know, thanks. And yes, I do have
backups but its kind of a pain to have to restore a whole system when
you have better things to do ;-)

Hmm, just curious: Is it really important for mkfs.* what the partition type 
is? Would they refuse to create a filesystem on say an NTFS partition? If 
not, would I get into trouble later, if I forgot to change the type?

Not to my knowledge. Actually, there isn't even a part. type for
reiserfs. And that also wouldn't make much sense, I think, because
those are *PARTITION* types, while reiserfs is a *FILE* *SYSTEM* type.

I don't see how.

Hm - UNTESTED: What happens, if you've got a JFS on a "NTFS partition"
and then boot Windows?

It's probably being reported as non-formatted media. Windows will offer
to format it, then. Click "OK", and your shiny JFS is gone :-)
