ASUS T103 HAF and Bitlocker

#1

Post by giogio » Mon Sep 24, 2018 8:33 am

Hi,
just bought a new ASUS Transformer Mini T103HAF-GR033T, 120GB with windows 10.
After configuring the machine as asked by the system (i.e. with windows 10) I tried to test if it is able to run MX linux (MX 17 64 bit live).
My goal is to see if the live session is working fine, if so trying to install to the SSD, if it is not possible, trying to put the system on a mini flash for a dual boot.

After booting from USB key (pressing ESC at the boot sent me on the boot menu allowing to select the USB key as a boot device) my MX went on and seemed to work fine, apart the screen fixed on vertical position. At this point I wanted to stop the machine looking for a way to see the screen the horizontal way.

After that, I tried to restart the machine, but this was locked by the request to insert the code for bitlocker.

So i discovered my windows partition was - by default, no one asked me about that - crypted by means of bitlocker.
After recovering my key (connection to microsoft site to get it : nothing while configuring the machine asked me to save something like this) I was able to see again my windows machine.

This was done while just running MX live, without trying to access to the hard disk (ssd), so now I am afraid to go on with my test with it.

Is someone aware of how it is possible to treat this strange bitlocker problem? They (Asus and Microsoft) created it to be "GDPR conform", but in my opinion it is just another trick to not let you use another operating system.

Thank you all

Re: ASUS T103 HAF and Bitlocker - hardware compatible?

Just a few updates.
I discovered the very hided voice to disable the bitlocker. After that I disabled it, the partition went uncrypted and I was able to going on.
I booted via usb MX Linux (pressing esc at start up to select the booting device). After a while I was able to boot, I saw the screen the vertical way only, so I had to rotate it, using the screen rotate option in MX.
At the moment, the keyboard is ok, the pen does not work fine, the touch screen has a few problem (sometimes), the touch pad is working fine, the wifi is running fine, the sound does not work.
On next days I will go deeper in its use.

According to Asus it is impossible to boot from the microSD that is not seen by the bios. So it is only seen by windows as an archive disk "D".
This means that MX booting from USB cannot see the microSD.
Maybe I can install MX on the main partition after resizing windows, but not so sure the machine will allow a dual boot.

Re: ASUS T103 HAF and Bitlocker - Grub unknown filesystem

#6

Post by giogio » Sun Jul 14, 2019 1:37 pm

Something changed. With version 18.3 I was able to install MX on a microSD and tried to boot it.
The Asus machine shows the possibility to boot from the installed MX18.3, but if I try to boot from this what I get is :
grub > unknown file system (two different messages)
grub > rescue
If I try with the command "ls" what I get is:
(hd0)(hd1)(hd1,gpt4)(hd1,gpt3)(hd1,gpt2)(hd1,gpt1)(hd2)(hd3)

The answer if I try a command like:
ls (hd2)

on every element on the above line always gives me the message of unknown file system.

I installed MX as ESP on the microSD using an image via USB.

So it seems grub is not able to see my installation.

If from the booted USB I try to see my installed MX on the microSD i see all the files (by the way I tried to see the two partitions created on the microSD, and the one marked as Vfat seems void)

Is there any way to keep grub working fine on the microSD?

Thank you for any suggestions.

With some more info ... may be,
e.g. something like those:
-> Quick System Info
-> lsblk -f
-> parted -l

HI,
the exit is something like the following:

sda->sda1 vfat ANTIXLIVE this is my usb boot device
mmcbk0 ->
mmcblk0p1 vfat system a serial number
mmblk0p2
mmcblk0p3 ntfs OS windows id number
mmcblk0p4 ntfs RECOVERY id number of recovery

mmcblk0boot0
mmcblk0boot1
mmcblk1 ->
mmcblk1p1 vfat a serial number like
mmcblk1p2 ext4 rootMX18.3 ID NUMBER
MMCBLK1P3 SWAP swapMX ID NUMBER

the parted command says something general and about the sd

model : SD SC64G (sd/mmc)
disk /dev/mmcblk1 : 63.9GB
sector size (logical/physical) 512B/512B
partition table : gpt

Disk Flags:
1 1949 kb --- other data ESP boot,esp
2 268MB 61,7GB 61,4 GB ext4 primary
3 61.5GB 63,8 GB 2147 MB linux-swap primary

Error: /dev/mmcblkboot1: unrecognised disk label
Node: generic SD/MMC Storage Card
Disk /dev/mcblk0boot1: 4194KB
Sector size (logical/physical) 512B/512B
Partition Table:unknown
Disk Flags:

After that there is nothing else.

I suspect the problem is under a trick of Asus,because if I put the ESP on the SD there is no possibility to boot (it is not appearing on the boot list when you press the esc key at boot time).

Maybe I will try to install MX on the main storage device, but I have to reduce windows, something I cannot do now.

Please post again the output of

Code: Select all

sudo parted --list
But this time please between those [code]code-tags [/code], otherwise it's hard to read and to decipher.
MX Tools -> "Quick System Info" was also requested.
