My arch was installed on sda3, debian was installed on sda2.

To enter into arch ,i want to mount /dev/sda2.
sudo mount -t boot -o rw /dev/sda2 /tmp
sudo mount -o rw /dev/sda2 /tmp
None of them can mount it.

How did you install Arch?
Offline
I install arch this way.
1.To enter into debian,and download arch iso file.
2. dd if=arch.iso of=/dev/sdb
3.boot with usb
4.do as the manual in arch wiki.

...and yet you don't know how to mount a partition?
And what do you think mounting your /boot on /tmp will actually achieve? How will that "enter into arch"?

Hey Yufeiluo,
Have you tried consulting the man page of mount?`man mount`
Also what type of filesystem are you attempting to mount and what command are you using for that?
Offline
You'll never be able to mount sda2 as it's a GRUB BIOS boot partition which doesn't contain a filesystem.
It's only used to store the grub payload which would usually live in the post-MBR gap on an ms-dos partitioned drive.
It's only meant to be 2MB in size, I've no idea why you made yours 37GB?

Edit - I see sda2 has the label debian, if this was your debian partition that you've changed the partition type on then you've really messed up the installation somehow.
