I have installed Debian 11 on a Dell T1650 Desktop PC (i7 & 24 GB RAM).
I resized the 1GB HD leaving 300MB on which I installed Debian. At the request of the installation of Grub I indicated the HD. Now looking at it with Gparted the HD is divided as follows: dev / sda1 EFI system partition (fat32) 100 MiB dev / sda2 Microsoft reserved Partition (unknown) 16MiB dev / sda3 Basic data partition (ntfs) 629.28 GiB dev / sda5 grub2 core.img 1.00 MiB dev / sda6 ext4 27.94 GiB dev / sda7 linux-swap 977.00 MiB dev / sda8 ext4 272.71 GiB dev / sda4 ntfs 520.00 MiB not allocated not allocated 1.71 MiB What would be better to do to get Grub up and running? Can I do something to be able to boot on 2 OS (Windows 10 & Debian 11) Or do I have to make use of rEFInd? The boot is in UEFI mode. Thanks for help Francesco
