Can't mount drive in rescue mode

[ZombieRevolver]

I am trying to mount my drive in linux netboot rescue mode in ovh servers.

I tried 'mount /dev/sda1 /mnt/'

and
I get this error:

mount: block device /dev/sda1 is write-protected , mounting read-only
NTFS signature is missing.
Failed to mounte '/dev/sda1': Invalid argument
The device '/dev/sda1':Invalid arugment
The device '/dev/sda1'/ deosnt' seem to have a valid NTFS.
May the wrong device is used? Or the whole disk instead of a partition?

My fdisk -l

WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

Please read your error messages.

You "told" the computer that /dev/sda1 is an NTFS filesystem. When mount tries to mount that mount says it can't find an NTFS filesystem.

Use the -t argument to mount to specify the filesystem to mount.
