Uninstall/delete one Linux distro without deleting/damaging /home partition

I have a quite complex setup of disks containing OSs in my computer: There are two HDD drives containing Windows XP, Windows 7, and a Linux. This all was running well, but I decided to buy an SDD additionally and installed a second Linux there. For both Linux installations I used separate partitions for mount point /home. Now I would like to uninstall/delete the Linux on the HDD, because the one on the SDD works well and is faster. **I want to make sure two things:** a) the /home partition on HDD stays and I can keep on using it from the SDD Linux (currently I can, I see both the /home on SDD and the "/home-hdd" on the HDD b) all other OSs remain bootable **Is it save for me to just wipe the HDD partition containing the Linux and its swap? Or do I have to take any precautions or changes before that?** Follow-up question: What partitions do I have to delete? From the HDD Linux point of view: / (root), /swap, and /opt. Obviously not /home. But what about /boot? UPDATE: This is the output of *lsblk* from the SDD Linux: NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS loop0 7:0 0 179,4M 1 loop /snap/chromium/3121 loop1 7:1 0 4K 1 loop /snap/bare/5 loop2 7:2 0 179,5M 1 loop /snap/chromium/3125 loop3 7:3 0 73,9M 1 loop /snap/core22/1908 loop4 7:4 0 73,9M 1 loop /snap/core22/1963 loop5 7:5 0 68,4M 1 loop /snap/cups/1085 loop6 7:6 0 67,2M 1 loop /snap/cups/1100 loop7 7:7 0 505,1M 1 loop /snap/gnome-42-2204/176 loop8 7:8 0 516M 1 loop /snap/gnome-42-2204/202 loop9 7:9 0 91,7M 1 loop /snap/gtk-common-themes/1535 loop10 7:10 0 44,4M 1 loop /snap/snapd/23771 loop11 7:11 0 50,9M 1 loop /snap/snapd/24505 sda 8:0 0 931,5G 0 disk ├─sda1 8:1 0 150G 0 part └─sda2 8:2 0 781,5G 0 part sdb 8:16 0 1,8T 0 disk ├─sdb1 8:17 0 100,6G 0 part ├─sdb3 8:19 0 512B 0 part ├─sdb5 8:21 0 814,4G 0 part ├─sdb6 8:22 0 186,3G 0 part /home-hdd ├─sdb7 8:23 0 37,3G 0 part ├─sdb8 8:24 0 458,2G 0 part ├─sdb9 8:25 0 9,3G 0 part ├─sdb10 8:26 0 7,4G 0 part └─sdb11 8:27 0 249,6G 0 part sdc 8:32 0 238,5G 0 disk ├─sdc1 8:33 0 58,6G 0 part / ├─sdc2 8:34 0 14,6G 0 part │ └─cryptswap 252:0 0 14,6G 0 crypt [SWAP] ├─sdc3 8:35 0 1K 0 part ├─sdc5 8:37 0 135,9G 0 part /home └─sdc6 8:38 0 29,3G 0 part /opt sr0 11:0 1 1024M 0 rom I hope this helps :)
