Environment

Issue
- How do I do to fix /dev/sda1 as a boot partition when installing?
Resolution
In setting partitions on anaconda, you can't do it.
When you see the setting, you can move to CUI console by entering Ctrl+Alt+F2, and do partitioning as you expected by using fdisk command.
1. Change to CUI console by entering Ctrl-Alt+F2 during the following screen.
- Install Red Hat Enterprise Linux Server
- Upgrade an existing Installation
2. Set partition with fdisk command
Example of setting partition for /boot:
# fdisk /dev/sda
command (m for help): p <- confirm partition information
Disk /dev/sda: 4294 MB, 4294967296 bytes
255 heads, 63 sectors/track, 522 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 1 522 4192933+ 83 Linux
command (m for help): d <- remove the above partition
Selected partition 1
command (m for help): p <- confirm partition information
Disk /dev/sda: 4294 MB, 4294967296 bytes
255 heads, 63 sectors/track, 522 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
command (m for help): n <- create a new partition
command action
e extended
p primary partition (1-4)
p <- select primary partition (enter 'p')
Partition number (1-4): 1 <- configure /dev/sda1
First cylinder (1-522, default 1): <- enter 'Enter'
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-522, default 522): +250M
command (m for help): p <- confirm partition information
Disk /dev/sda: 4294 MB, 4294967296 bytes
255 heads, 63 sectors/track, 522 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 1 31 248976 83 Linux
Not need to set a partition type.
3. Go back to anaconda screen with Ctrl + Alt + F6
Select the below and proceed.
- Install Red Hat Enterprise Linux Server
4. Select 'Create custom layout'
5. Configure each label, format and type of partition
In addition, after installation, you can't change partition name for / and /boot.
