Dual boot fails on Lenovo ThinkCentre with Windows 10
https://askubuntu.com/questions/1568631/dual-boot-fails-on-lenovo-thinkcentre-with-windows-10
Initially I succeeded in installing Ubuntu 24.04 in parallel to Windows 10, but even after repairing the boot partition with Boot-Repair (https://paste.debian.net/hidden/bc192e4d) I don't get the system working, because it fails to find the boot partition.

Recommended repair: ____________________________________________________________
The default repair of the Boot-Repair utility will purge (in order to remove grub-efi) and reinstall the grub2 of
sda4 into the MBR of sda.
Grub-efi will not be selected by default because no ESP detected.
Additional repair will be performed: unhide-bootmenu-10s win-legacy-basic-fix
/boot/efi removed in sda4/fstab
Quantity of real Windows: 1
WinSE in sda2
Copied Win boot files from sda1 to sda2
chroot /mnt/boot-sav/sda4 apt-get -y update
Purge the GRUB of /dev/sda4

Bitte stellen Sie sicher, dass Ihr BIOS von sda (ATA SAMSUNG MZ7LH480) startet!
Die Startdateien für [sda4 (end>100GB)] liegen weit hinten auf der Festplatte. Ihr BIOS könnte sie nicht erkennen. Bitte legen Sie eine Partition vom Typ /boot an und versuchen es ggf. erneut. (EXT4, >200MB, Anfang des Datenträgers). Das könnte mit Werkzeugen wie gParted geschehen. Danach wählen Sie diese Partition über Option [Separate /boot-Partition:] von [Startreparatur]. (https://help.ubuntu.com/community/BootPartition)Bitte setzen Sie Ihr BIOS in den Legacy-Modus, um Ihr Ubuntu 24.04.3 LTS zu starten, und geben Sie dann den Befehl [sudo update-grub] ein, um den Eintrag Windows in Ihr GRUB-Menü aufzunehmen.

I hesitate to follow the advice to increase sda1 on linux because it would end up in resizing sda2 (Windows 7/8/10 partitions should only be modified by windows tools!?) ...
The final advice of boot-repair '... Finally select sda1 as [Separate /boot-Partition:] in register [Startreparatur] ...) could not be followed, because on my live-ubuntu sda1 wasn't detected, thus it couldn't be selected. ...
What would be the best solution?
Would it be possible to follow the aforementioned advice while running Boot-Repair from a live image or isn't sda1 big enough? Is there a console command to point from sda1 to sda4?
