I've seen posts in the past that advise against changing the partition number but like Fox Mulder: " All the evidence to the contrary is not entirely dissuasive "
I have an old MBR disk that I used to boot from before I install Ubuntu on a faster M.2 ssd. I now want to remove my old Win8 partitions and give the space back to Linux
fdisk /dev/sda Disk /dev/sda: 1.8 TiB, 2000398934016 bytes, 3907029168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x3457a860 Device Boot Start End Sectors Size Id Type /dev/sda1 * 2048 524290047 524288000 250G 7 HPFS/NTFS/exFAT /dev/sda2 524290048 548290559 24000512 11.5G 82 Linux swap / Solaris /dev/sda3 548292606 648290303 99997698 47.7G 5 Extended /dev/sda4 648290304 3907028991 3258738688 1.5T 83 Linux /dev/sda5 548292608 648290303 99997696 47.7G 83 Linux
The only partition that I use is sda4.
sda1 was my old Win8 dual boot partition
sda2 was for swap but now I'm running on a separate ssd
sda5 was for /boot before my current ssd
Is is possible to delete sda1, sda2 and sda5 and perform something like e2fsresize to grow my ext4 filesystem into the extra space and then rename sda4 to sda1?
I rather not resort to buying a new 2TB drive just so I can backup my files and repartition the whole disk.
