>Description:
NetBSD 9.0-RC2 does not install on an ASUS X202E laptop with GPT
partitions.

1. The standard installation seems to want to use my Linux ext4
partition as the NetBSD partition to install to (it show the
NetBSD partition to be installed to have a size of 278G which is
the size of the Linux ext4 partition.), so I drop to a shell and
add 3 partitions for NetBSD as in this URL:

https://wiki.netbsd.org/Installation_on_UEFI_systems/

Here's the GPT layout:
$ sudo gdisk /dev/sda
GPT fdisk (gdisk) version 1.0.3

Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: present

Found valid GPT with protective MBR; using GPT.

Command (? for help): p
Disk /dev/sda: 976773168 sectors, 465.8 GiB
Model: ST500LT012-9WS14
Sector size (logical/physical): 512/4096 bytes
Disk identifier (GUID): A6E9090D-B5AB-412A-8568-2EEE08FA3FA8
Partition table holds up to 128 entries
Main partition table begins at sector 2 and ends at sector 33
First usable sector is 34, last usable sector is 976773134
Partitions will be aligned on 2048-sector boundaries
Total free space is 146911213 sectors (70.1 GiB)

  11       220745728       229134335   4.0 GiB     A901  NetBSD swap

Command (? for help): 

2. Exit shell, to go back to the main Install System screen.

3. Choose 'a' to Install NetBSD to hard disk.

4. Choose 'b' to continue.

5. Choose dk10@wd0, the manually created/formatted partition, as the
disk to install to.

6. Choose 'b' to continue.

7. Choose 'a' Yes to use the swap detected.

And now the installer goes back to the main Install System screen
without doing anything. If I leave the NetBSD partition unformatted,
the installer formats the partition, then goes back to the Install
System screen.
