32 bit EFI Linx-7 tablet dual boot
- The Linx-7 Tablet is an Intel based tablet.
- It comes with Win 8.1 (32 bit) in UEFI mode so has a 32bit EFI
Now, Mageia-7 Live 32 has UEFI mode available, so with some patience, it can become a dual boot with Windows and Mageia, or if you like, a Mageia only tablet.
below is how I set up a Linx-7 tablet for dual boot:
- Linx-7 tablet with fully charged battery
- OTG adapter lead
- multi port usb hub
- usb keyboard
- usb mouse
- Mageia 7 Live USB key
- Plenty of Patience
First, the usual windows preparation:
Boot into Windows.
change the operation of the power off to "shutdown" not "hibernate":
from the main menu, choose PC Setting, => Control Panel.
in the search window search for "Power Options", click on "change what power buttons do".
after this, need to create a partition space for Mageia.
may need to exchange keyboard for mouse and vis-versa connection to OTG adapter lead for the following.
first need to disable the page file:
Select Advanced system settings.
Select the Advanced tab and then the Performance radio button.
Select the Change box under Virtual memory.
Un-check Automatically manage paging file size for all drives.
Select No paging file, and click the Set button.
now, to defragment the drive:
right click computer icon and choose defragment.
now to create the Mageia partition:
in the Control Panel search window enter "disk"
from the options presented choose: "create and format harddisk partitions"
choose the largest partition (~26GB) and reduce it by approx 50%
this will create the empty space that Mageia installer will use.
reboot the unit and confirm that windows will reboot correctly.
power off the unit
connect the OTG adapter lead to the multi port USB hub and connect keyboard and USB key.
boot up and enter the bios:
use Esc or Del keys
under "Advanced" tab options in bios, select OS/BOM configuration and choose =>ISP PCI Device Selection and choose =>ISP PCI Devce as B0D3F0
move on to "Security" tab disable "Secure Boot"
move on to "Boot" tab.
Here, disable "Fast Boot"
move down to "Boot Option Priorities"
here change the boot order:
disable "Windows Boot Manager" and add "UEFI: USB Flash Drive"
save and exit bios (F4)
reboot and re-enter bios
Go to "Save and Exit" tab
go to "Boot Overide"and choose UEFI USB (should have the Manufacturer name of the USB key)
press enter on keyboard
You should now be presented with the USB Live boot menu.
Choose the "Boot Mageia Live" or "Install Mageia Live" and "enter"
it is slow, so be patient!
you can now disconnect the keyboard as the installer can use the touch screen to complete the install, either from the desktop icon or the boot menu.
if the desktop live installer icon fails to initialise, open a terminal, reconnect the keyboard and enter:
this will start the installer.
set up the disk partitions as usual and follow the prompts.
If you thought the boot to Live desktop is slow, be prepared for a very long wait.
at completion, reboot, disconnect the multi port usb hub, reconnect the keyboard and re-enter the bios.
Check the "Boot" tab and check that Mageia is the first in the boot order.
if so "F4"and continue the install process.
Keyboard is now required to set up root user password, user name and password, and if you did not choose "Gnome", keyboard is needed for login.
after desktop is presented you can setup the wifi and then online repos as is usual, and update the system.
reboot and grub2 boot menu should present Windows as an option and Mageia entries also.
HP Probook 4520s core i5 (SSD) systemd-analyze time
Startup finished in 6.379s (kernel) + 18.889s (userspace) = 25.269s
Linx-7 tablet systemd-analyze time
Startup finished in 6.450s (kernel) + 12.892s (userspace) = 18.907s
A keyboard is required to change between grub entries (and login if not using Gnome, and any text input for terminal work or text input boxes.)
Cameras are not detected.
In Xfce, volume buttons do not work, but do in Gnome and yes ....Plasma5
Desktop is in "Portrait" mode
to change you need to install xrandr packages :
this will allow you to change from portrait to landscape mode
xrandr --output DSI1 --rotate left (or right)
now display is in landscape mode, but touchpad mouse is in portrait mode!
xrandr --output DSI1 --rotate normal
returns to portrait mode
