Windows Server 2022 Installation failed

[1stNeferpitou]

• OVH dedicated server
• UEFI mode
• CBS ERROR_FILE_NOT_FOUND during oobeSystem
• Microsoft-Windows-Shell-Setup component fails

tried to install Windows Server 2022 but I faced a lot of problems

`# 1. Mount EFI
mkdir -p /boot/efi
mount /dev/nvme0n1p1 /boot/efi

2. Put .efi file so reinstall script detects EFI partition

apt-get install -y -qq grub-efi-amd64-bin
mkdir -p /boot/efi/EFI/BOOT
cp /usr/lib/grub/x86_64-efi/monolithic/grubx64.efi /boot/efi/EFI/BOOT/BOOTX64.EFI

3. Download reinstall script

curl -fsSL https://raw.githubusercontent.com/bin456789/reinstall/main/reinstall.sh -o reinstall.sh

4. Patch rootfs detection bug (OVH rescue has no real / block device)

LINE=$(grep -n 'mapper=$(mount' reinstall.sh | cut -d: -f1)
sed -i "${LINE}s|.*| mapper=/dev/nvme0n1|" reinstall.sh

5. Run install (will prompt for password)

bash reinstall.sh windows
--image-name 'Windows Server 2022 SERVERDATACENTER'
--iso 'https://software-static.download.prss.microsoft.com/sg/download/888969d5-f34g-4e03-ac9d-1f9786c66749/SERVER_EVAL_x64FRE_en-us.iso'
--lang en-us
--password 'Admin12345'

6. Fix GRUB - copy vmlinuz and initrd to EFI partition

mkdir -p /boot/efi/EFI/reinstall
curl -Lo /boot/efi/EFI/reinstall/reinstall-vmlinuz
http://dl-cdn.alpinelinux.org/alpine/v3.23/releases/x86_64/netboot/vmlinuz-lts
curl -Lo /boot/efi/EFI/reinstall/reinstall-initrd
http://dl-cdn.alpinelinux.org/alpine/v3.23/releases/x86_64/netboot/initramfs-lts

7. Fix grub.cfg paths

sed -i 's|search --no-floppy --file --set=root /reinstall-vmlinuz|set root=(hd1,gpt1)|' /boot/efi/EFI/reinstall/grub.cfg
sed -i 's| /reinstall-vmlinuz | /EFI/reinstall/reinstall-vmlinuz |' /boot/efi/EFI/reinstall/grub.cfg
sed -i 's|initrd /reinstall-initrd|initrd /EFI/reinstall/reinstall-initrd|' /boot/efi/EFI/reinstall/grub.cfg

8. Verify

echo "===== grub.cfg ====="
cat /boot/efi/EFI/reinstall/grub.cfg
echo "===== DONE - Change boot to hard disk in OVH Control Panel then reboot ====="
`
that script works good but since I did the grup manually it doesn't run the script from alpine automatically

installation can't complete

[1stNeferpitou]

would
--force-old-windows-setup 1
--force-boot-mode bios
fixing the problem with bare metal like OVH ?

[bin456789]

cant run the script in rescue mode

[1stNeferpitou]

cant run the script in rescue mode

I run it first at rescue mode then after I reboot on Harddisk I run it one more time on alpin

[1stNeferpitou]

so running it at rescue mode made all these problems ? what's the best OS if I want to setup windows on a dedicated server ?

[bin456789]

Change boot to hard disk in OVH Control Panel.
then run the script
