My new laptop's OS was trashed by a failed global software update. The HDD is partitioned thus (ignore sdb1, the live-USB and sdc1, another USB stick):
ubuntu@ubuntu:~$ lsblk -f
NAME FSTYPE LABEL MOUNTPOINT
sda
├─sda1
├─sda2
├─sda3
└─sda4 [SWAP]
sdb
└─sdb1 /cdrom
sdc
└─sdc1 /media/ubuntu/TRANSFER
loop0 /rofs
or, maybe more usefully:
ubuntu@ubuntu:~$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 465.8G 0 disk
├─sda1 8:1 0 500M 0 part
├─sda2 8:2 0 3G 0 part
├─sda3 8:3 0 454.5G 0 part
└─sda4 8:4 0 7.8G 0 part [SWAP]
sdb 8:16 1 3.8G 0 disk
└─sdb1 8:17 1 3.8G 0 part /cdrom
sdc 8:32 1 1.9G 0 disk
└─sdc1 8:33 1 1.9G 0 part /media/ubuntu/TRANSFER
loop0 7:0 0 1007.1M 1 loop /rofs
Having read Mike McGrath's Linux in Easy Steps (5th edition) sda2 must be the OS (/), sda3 must be where all the user-created files are (/home) and sda4 is the Swap (the book says this should be roughly double the Ram size - the laptop has 4GB Ram).
Q1: What's that 500MB partition?
Q2: The book says to specify 7-10GB partition for the OS - why is Dell's only 3GB?
