Dual Boot, Windows 10 PRO, Linux - CentOS 8, Menu disappears, Lenovo Laptop

I was using CentOS 8 in my Laptop dual with Windows 10 Pro, recently I made an update and the Menu is not shown, only boot on Windows 10 Pro directly. The Boot Mode Originally was in UEFI mode. I don't changed! I changed the Boot Priority Order From To I restarted, But the Menu doesn't appears! Later, I selected Legacy Options Restarted, but it change doesn’t works This one doesn’t work either. Originally Security Boot was Enabled Later I disabled some Security options like: Security Boot and Security Chip I update to Disabled I would like to recover the menu, in order to select which OS I want to use (CentOS 8, or Windows 10 PRO). Unfortunately, that Changes doesn't works! My Laptop is a Lenovo, but I'm not sure what BIOS settings I need to select in order to recover the Menu. **What settings boot options should I select?** Thanks for your Help. **EDIT 3**: Previously I had this settings https://unix.stackexchange.com/q/654060/400726 And I had the previous Issue https://unix.stackexchange.com/q/607292/400726 Now I have C:\Users λ bcdedit /enum firmware Firmware Boot Manager --------------------- identifier {fwbootmgr} displayorder {1fa1f7db-9958-11ea-a843-806e6f6e6963} {1fa1f7e0-9958-11ea-a843-806e6f6e6963} {bootmgr} {1fa1f7dd-9958-11ea-a843-806e6f6e6963} {1fa1f7de-9958-11ea-a843-806e6f6e6963} {1fa1f7df-9958-11ea-a843-806e6f6e6963} {1fa1f7e1-9958-11ea-a843-806e6f6e6963} {1fa1f7e2-9958-11ea-a843-806e6f6e6963} {1fa1f7e3-9958-11ea-a843-806e6f6e6963} timeout 0 Windows Boot Manager -------------------- identifier {bootmgr} device partition=\Device\HarddiskVolume1 path \EFI\Microsoft\Boot\bootmgfw.efi description Windows Boot Manager locale es-ES inherit {globalsettings} default {current} resumeobject {a8801e99-ce19-11ea-aa82-c858c03abd0c} displayorder {current} toolsdisplayorder {memdiag} timeout 0 Firmware Application (101fffff) ------------------------------- identifier {1fa1f7d9-9958-11ea-a843-806e6f6e6963} description Setup badmemoryaccess Yes Firmware Application (101fffff) ------------------------------- identifier {1fa1f7da-9958-11ea-a843-806e6f6e6963} description Boot Menu badmemoryaccess Yes Firmware Application (101fffff) ------------------------------- identifier {1fa1f7db-9958-11ea-a843-806e6f6e6963} description NVMe: SKHynix_HFM512GDHTNI-87A0B badmemoryaccess Yes Firmware Application (101fffff) ------------------------------- identifier {1fa1f7dc-9958-11ea-a843-806e6f6e6963} description UEFI Diagnostics badmemoryaccess Yes Firmware Application (101fffff) ------------------------------- identifier {1fa1f7dd-9958-11ea-a843-806e6f6e6963} description ATA HDD: badmemoryaccess Yes Firmware Application (101fffff) ------------------------------- identifier {1fa1f7de-9958-11ea-a843-806e6f6e6963} description ATA HDD: badmemoryaccess Yes Firmware Application (101fffff) ------------------------------- identifier {1fa1f7df-9958-11ea-a843-806e6f6e6963} description ATAPI CD: badmemoryaccess Yes Firmware Application (101fffff) ------------------------------- identifier {1fa1f7e0-9958-11ea-a843-806e6f6e6963} description USB HDD: SanDisk Ultra Fit badmemoryaccess Yes Firmware Application (101fffff) ------------------------------- identifier {1fa1f7e1-9958-11ea-a843-806e6f6e6963} description PCI LAN: badmemoryaccess Yes Firmware Application (101fffff) ------------------------------- identifier {1fa1f7e2-9958-11ea-a843-806e6f6e6963} description USB FDD: badmemoryaccess Yes Firmware Application (101fffff) ------------------------------- identifier {1fa1f7e3-9958-11ea-a843-806e6f6e6963} description USB CD: badmemoryaccess Yes C:\Users λ **EDIT 2**: I was using a USB3.0 HDMI Video Capture, I'm using OBS I was able to record a video when I tried to check with https://sourceforge.net/projects/supergrub2/files/2.04s2-beta2/super_grub2_disk_2.04s2-beta2/supergrub2-2.04s2-beta2-multiarch-USB.img.zip/download Here the videos. https://drive.google.com/file/d/1fpidK2-fujdPwT7PhoFL40cuRfy8rPQ6/view https://drive.google.com/file/d/1IHiZBCssViHakxLly3HudC4eKiShvAzM/view **NOTE 1**: I have access to Read/Write from Windows 10 over Linux Partitions using EXT4 FileSystem.
