more:
when in DVD OS
just mount whatever your partition is that you are going to put home on in your /tmp ogg the DVD os.

Code:

sudo mkdir -pv /tmp/home/username 
or
sudo mkdir -v /tmp/home

that all depending on how you want to handle adding a user, and
the -p is just to make more than one directory at a time.
then as you see root owns home or 0755 but root cteation of home and leave it alone - I'll never had any issues in doing it that way.

Code:

userx%voider ⚡ ~ ⚡> ls -la /home
total 40
drwxr-xr-x  7 root  root   4096 Jun 30 09:49 .
drwxr-xr-x 17 root  root   4096 Apr 26 09:00 ..
drwxr-xr-x  2 root  root   4096 Apr 20 17:57 ftp
drwx------  2 root  root  16384 Mar  4 07:56 lost+found
drwx--x--x 27  1001 users  4096 Jul  7 08:14 surooterdude
drwx--x--x 44 userx users  4096 Jul 10 07:28 userx
drwx--x--x 50 userx users  4096 Jun 19 15:53 userx-bk

it is the user and own his own 'home' under /home that needs to be sure it has proper UID. If you did not or do not delete that user prior to doing all of this then it is a changing permissions that may need to be done on that /home/USER directory that maybe needed.

then this is bad information

Code:

/root /dev/sda1 <-- linux is root not windows
/home /dev/sda2
/swap /dev/sda3 <-- same as
NTFS /dev/sda3 <-- this

which I already pointed out the sda3 thing

regardless all of the steps are the same it is just the partitions numbering that changes is all.

<username> is the name of the user's folder in /home, usually the same name as the user's login name. Then you will have to use chown command to change ownership of the folder to the user.

more thoughts..
if you do not have your Linux split into two seleprate / and /home then you cannot delete /home and expect your Linux OS to still be there. as you have not provided proper information on how you HDD is really split up and used I cannot give you exact how to's

Code:

fdisk -l /dev/sda

copy paste the results of that back so everyone can see what is really going on. thank you.
it should look something like this. as this is what is really needed.

Code:

Device     Boot     Start       End   Sectors   Size Id Type
/dev/sda1  *         2048   1026047   1024000   500M  7 HPFS/NTFS/exFAT
/dev/sda2         1028160 204902463 203874304  97.2G  7 HPFS/NTFS/exFAT
/dev/sda3       204906496 205828095    921600   450M 27 Hidden NTFS WinRE
/dev/sda4       205828096 488397167 282569072 134.8G  5 Extended
/dev/sda5       205830144 249968639  44138496    21G 83 Linux
/dev/sda6       249970688 303507455  53536768  25.5G 83 Linux
/dev/sda7       303509504 488396799 184887296  88.2G 83 Linux

that is strange indeed. you are using LINUX to do this?
if you're root then you should not be having any problems. I do this all of the time, or have with my dual boot, whenever I screw up something by forgetting to do it right - I just boot into my other linux mount make needed changes to fix it using su or sudo no problems.

but this is Ubutututu and in my option are a screwed up OS due to how they control root account.

by rights you should be able to just be in root and do whatever to whatever because it is root.

you must have missed something,

try using sudo regardless where you're logged into. or 'whoami' to be sure your root.

Code:

good morning userx
userx%voider ⚡ ~ ⚡> whoami
userx
userx%voider ⚡ ~ ⚡> su
Password:
(root@voider⚡️/home/userx)>># whoami
root
(root@voider⚡️/home/userx)>>#
