Awesome. I feel more confident about the install now. I am sure I will have questions after completing the install and reading the manuals.

If you're using fdisk to partition the drive, you have to specify the beginning and ending sector of each partition. I determined these using a calculator (a TI-84+ mind you; a pocket calculator most likely won't be sufficient).

You can also use cfdisk, which is a full-screen alternative to fdisk. I've never specified a partition size in cfdisk though, so I don't know how it's done.

Yikes the beginning and ending sectors. I dont know anything about that. I am going to re-watch the install tutorial on Youtube now.

This is done automatically in fdisk. You don't need to worry about it. Just specifying the size in G or whatever you will be able to just use the default sectors that fdisk indicates.

Basically what you want to do is take the starting/ending gigabyte, multiply by 2^30 to get the byte number, then divide by the sector size (usually 512, but it will say in fdisk if you type "p") to get the sector number.

With fdisk, you don't need to know about the sectors. By default, it will start with the first available sector, then you just specify the size you want... In other words, just use the defaults for the start, the actual size you want for the "Last sector" except for the last partition, just use the default last sector (as that'll use the full remaining amount of space on the drive. Here is a quick run through on one of my 1TB drives (with fdisk, so cfdisk will not look the same, but I'd assume the process would still be similar).

Code:
fdisk /dev/sdf

So do you mean you type, say, "10G" to specify a 10 GB partition? I did not know that. Still fairly new to fdisk.

Basically, yes. The expression would be "+10G" for 10 GB.

Dealers choice I suppose. I am using a BIOS/MBR setup so fdisk works perfectly for me and it is relatively easy.

If you're new to fdisk then please refrain from giving misleading advice to other users. Partitioning is not something done for fun and people who follow misleading, ill-informed advice run the risk of losing their data.

Just as a reminder, fdisk will prompt you on what it wants... just make sure you read everything it prints so you don't do the wrong thing.

Quote:
Last sector, +sectors or +size{K,M,G}
Basically, it will allow you to specify a specific sector you want to end at (just specify the actual sector you want it to end at), to create a partition how ever many sectors large you want it to be (put a plus sign in front of the number and it will make the partition that many sectors large), or you can use actual byte references to how big you want the partition (the plus sign followed by the size in K, M, or G (looks like I might've been incorrect in it letting you use T for terabytes, but fdisk doesn't support volumes over 2TBs anyway, so not supporting T isn't a huge deal)).

Probably muddied the waters with that one

Yes, and another problem with the `calculator approach` with modern advance format drives is if you get it wrong, performance will suck too.

These days, I trust fdisk -- it's way smarter than I am.

I am trying to write Slackware to USB via terminal. I tried

sudo dd if=/home/lucifer/Desktop/slackware64-14.1-iso of=/dev/sdb oflag=direct bs=1048576
I get this error:
dd: failed to open ‘/home/lucifer/Desktop/slackware64-14.1-iso’: No such file or directory

I tried dd if=/home/lucifer/Desktop/slackware64-14.1-iso of=/dev/sdb bs=1M

and

if=/home/lucifer/Desktop/slackware64-14.1-iso of=/dev/sdb


lucifer@lucifer-Satellite-C655:~/Desktop/lxle-14.04.4-64bit$ sudo dd if=/home/lucifer/Desktop/slackware64-14.1-iso of=/dev/sdb oflag=direct bs=1048576
dd: error reading ‘/home/lucifer/Desktop/slackware64-14.1-iso’: Is a directory
0+0 records in
0+0 records out
0 bytes (0 B) copied, 0.00279267 s, 0.0 kB/s



Still no luck. Here is the output from sudo fdisk -l

Device Boot Start End Blocks Id System
/dev/sdb1p1 * 0 3088639 1544320 0 Empty
/dev/sdb1p2 3076268 3080811 2272 c W95 FAT32 (LBA)
