ThinkPad P52 boot issue

#1 Post by asma » Fri Mar 15, 2019 6:01 am

Hello everyone,

I installed linux (ubuntu 18.04) in dual boot with Windows 10 on my ThinkPad P52 laptop.
At the beginning, everything was going well.
Then, I installed NVIDIA drivers and I got some grub issues.
I tried to fix them by changing boot options(Legacy mode/ UEFI mode) and boot order ...
I tried to restore then default options by pressing F9 but
Now, I am not able to access windows and ubuntu.
When I turn on my computer, a repeated message came up in my screen:
--------------------------------------------
Broadcom UNDI PXE-2.1 v11.0.11
Copyright (c) 2000-2008 Broadcom Corporation
Copyright (c) 1997-2000 Intel Corporation
All rights reserved
PXE-E61: Media test failure, check cable
PXE-MOF: Existing Broadcom PXE ROM
-----------------------------------------------------------

And then, the boot menu appear ,
Windows and Ubuntu are not recognised and there is only those two entries:
nvme0 intel and PCI LAN

I tried to boot with a live USB and I verified that Windows and ubuntu partitions are always well installed in the system.

I run then LENOVO Diagnostics and I passed successfully all of them!!

Could you please help me to resolve this issue
Thank you!!

Looks like your main drive is not fitted properly.
Remove power, then take it out and reseat it.
Try again.

So, I tried to reset the laptop;

The following message disappeared
--------------------------------------------

BUT, I cannot access to Windows and Ubuntu, they still don't appear in the boot menu ...
There is only nvme0 intel and PCI LAN.

I am sure that both of Linux and Windows are well installed
but I don't know how to add them in the boot menu.

:oops:

Finally, I decided to solve the issue by reinstalling Windows from bootable USB,
Windows appear in the boot menu and it works well !!
I tried to reinstall Ubuntu 18.04 as well, but it still not recognized !
There is no grub menu when turn on the laptop,
Windows boot directly !!

Please let me know if you have any suggestions ..

Install a second drive for the second OS.
Or follow this: https://askubuntu.com/questions/826322/ ... clean-wipe

Thanks!

After trying many solutions,I find finally a way to solve that issue !!!!!!

From hard disk partitions in Windows, I deleted the ubuntu partition then extend this old partition with windows.
Again, I create a new empty partition by shrinking windows Volume!
Reinstall ubuntu in that new free partition!!

And that's it!
