Start the system from a live cd like parted magic and do it.
You need to create the table and then the partitions as root user in Fedora ... parted will be better

A tool like GParted will automatically create the partition table when you create one or more partitions.
What do you mean when you say "it doesn't do anything". What exactly happens? (Note that--with typical partitioning tools, you have to tell it explicity to write the new partition table.
You can also try something fdisk or cfdisk.
(And why do you want a partition with an "msdos label"?)

Hi,
Code:
parted /dev/sdb mklabel msdos
parted /dev/sdb mkpart primary ext2 0 10000
should create a new msdos label and a partition of size 10000 MB on /dev/sdb. Make sure that /dev/sdb is indeed the hdd you want to install on. Also make sure that there is no important data on /dev/sdb since it will be destroyed (the data that is, not the hdd itself).
Afterwards you can format the newly created partition /dev/sdb1 with mke2fs. |

For Linux on a PC, you should use MSDOS type label. Choosing the label can be confusing.

Make sure you know what a gpt disk is before you use it.

I'm confused...
None of my Linux partitions have labels---why would a label be needed?
For the OP: Are you still using GParted? If not, then which utility are you using?

pixellany,
Two things need clarification
(1) Some distros, like those from the Red Hat family, are keen with booting to a label and dislike the normal device name like /dev/sdax. They would create labels as this page in cfdisk shows. The labels can get complicated as more digits have to add to make each one unique.
Code:
cfdisk 2.12r
Disk Drive: /dev/hda
Size: 300090728448 bytes, 300.0 GB
Heads: 255 Sectors per Track: 63 Cylinders: 36483
Name Flags Part Type FS Type [Label] Size (MB)

In my old box with 145 operating systems the labels used are
Code:
root@KanotixBox:/home/saikee# ls /dev/disk
by-id by-label by-path by-uuid
root@KanotixBox:/home/saikee# ls /dev/disk/by-label
12 12345 12345678 1234567891011 123456789101114 123456789101117 123456789101120 123456789101124 HDA1
123 123456 123456789 123456789101112 123456789101115 123456789101118 123456789101121 400Gb-end-Z SLAMPP
1234 1234567 12345678910 123456789101113 123456789101116 123456789101119 123456789101123 Ark WIN3-11
If I have a need to alter a Grub I always change the label back to the normal device name. Can't remember seeing Lilo using label on a Linux though.
(2) The Parted sofware uses "label" to distinguish the two partitioning schemes of "msdos" and "gpt". That is just using label for a different reason. 99% of us use only the msdos disk. gpt disks are not detectable by many Linux software and can't be booted by most Windows. Only 64-bit version Windows can boot a gpt disk and this can only be done with efi hardware in the mobo. Linux can boot gpt disks a long time ago. It is only used for partitions and hard disks larger than 2TB at the moment but can have 128 partitions maximum.
