I have a dual boot Ubuntu on my Lenovo X230. Linux One is unencrypted on sda2 (family, guests, tinkering), Linux Two (work) is encrypted within sda5:
NAME TYPE FSTYPE MOUNTPOINT
sda disk
├─sda1 part ext2 /boot
├─sda2 part ==> my Linux One (Elementary OS)
└─sda5 part crypto_LUKS ==> my Linux Two (Ubuntu-Mate)
└─sda5_crypt crypt LVM2_member
├─ubuntu--vg-root lvm ext4 /
└─ubuntu--vg-swap_1 lvm swap [SWAP]
Question: If I boot from my Windows 10 boot media, install Windows to sda2 (overwriting my Linux One), what bad things will happen, that I need to look into before/after windows 10 install?
- What about the boot partion?
- What about restoring the bootsector afterwards? (I believe, I am on UEFI, on this 4-year-old machine…)
Can the Win10 install harm the other partitions? (within the W10 setup, of course I will go for „expert mode“ and picking the partition to install to...)
I'd assume, I better boot with a linux stick before and backup
/boot/grubbefore?
What will I have to do after windows install?
This question was marked as an exact duplicate. – It clearly is not: The partitioning situation is entirely different, bootloader already exists. No repartitioning. Ubuntu is already in a to-be-preserved placed. Including encryption. … :-/ – Frank N Feb 06 '18 at 09:51
