    Lenovo ThinkPad T420 with UEFI Only

    No. I am going back home now to try that. I must have missed that step when I read your guide. Thanks for the guidance! It was working with the config.patchedDSDT.plist file. But then I installed the kext from the clover of tluck’s guide and I can’t use the internal LCD monitor anymore. I will reinstall the Catalina tonight and see if it’s ok.

    I was getting stuck in a black screen until I figured out that the problem was the internal LCD monitor. I plugged an external monitor and Catalina was actually working fine! I used the config.patchedDSDT.plist Thank you for the support!

    I think I’m on the right path! I put the files fro tluck’s zip file in both usb stick and the HDD EFI partition. I was able to get the patched Catalina installer on a usb stick. Firstly, I booted from the clover usb stick. I did the APFS partition and started the installation. Then, after it rebooted, I booted directly from the HDD after the 1st step of the installation. Here is my screen now. I keep my fingers crossed!

    I tried that patcher but I changed the clover files before I install Catalina. After the restart my laptop wasn’t able to boot in macOS. So, I had to make a fresh installation. Is there any guide for a fresh installation of Catalina?

    Thank you for the support on the windows update question! Windows 10 is now running normally! So, I kept a backup from High Sierra partition, I downloaded a full copy of Catalina and I created a usb installer using the transmac app in windows. I’m trying to make a clean install of Catalina but it says I cannot. Here is a screenshot of the message that pops up. I used the disk utility from the installer to create an APFS partition.

    Lenovo ThinkPad T420 with UEFI Only

    Hello, I have a Lenovo T520 laptop with triple boot Windows 7, Mac OS and Linux(Kali). All operating systems are running from one SSD hard disk splitted into 3 partitions. Everything is working smoothly. I would like to upgrade the partition of Windows 7 to Windows 10. Is there any guide to follow on how to keep my current setup and just upgrade the Windows partiotion? Sorry if there has been answered before!

    Thank you for the reply! Could you please guide me as if I had a T420? I really want to avoid reinstalling everything from the beginning. I have this laptop perfectly working for 2 years and I was always following the guides from this great topic. Sent from my iPhone using Tapatalk

    Thank you for the reply! Here is my screen. After that point the screen turns black and then reboots. Sent from my iPhone using Tapatalk

    I am having boot loop after updating from App Store to 10.13.4! I have triple boot with Windows Mac OS and Linux. I see the bar loading, then screen goes off then reboot. I can boot in safe mode normally. I am having T520 but since now I had no problem following the updates from the App Store and all the guides of this post. Any ideas on how to fix this?
