Best to backup your data and reinstall LM as a single-boot.

That's definitely not necessary.

Best (most simple) approach: boot Mint from the DVD, launch GParted, and format the Windows partition(s) into a big storage partition (EXT4). You can use that for "dumb" storage from then on.

Then boot into your installed Mint and run this command:

Code: Select all

sudo update-grub

It is always better and faster to install the / or root or system partition at the beginning of the disk for a single-boot system, especially for a HDD.

Your recommendation will have the Linux / partition remain at or near the end of the disk = slower system. Also, your recommendation will likely bork the whole system because the Windows Boot Partition where Grub is installed has been formatted or deleted.

That is also why the MBR Boot Partition or EFI System/Boot Partition and their associated bootloaders should be installed at the beginning of the disk = faster boot time.

Slower by how much? 0.5 milliseconds?

That has already been debunked by catweazel, so I won't comment on that.

Obviously, that partition shouldn't be touched because it's not a Windows partition, but a general purpose partition which also caters to Linux. It's indeed useful to point this out to the OP.

Let's cut the fud.

Open a terminal and post the output of

Code: Select all

sudo parted -l

His statement (an absolute time) didn't make any sense when speaking of transfer speeds, so I wouldn't call it a debunking; I'd call it a conceptual error.

https://www.pcworld.com/article/255224/ ... mance.html
"For this article, we tested a 1TB Western Digital Velociraptor drive and initially saw transfer rates in the vicinity of 210 megabytes per second, which gradually slowed to about 116 MBps. Similarly, access times were fastest in the early part of the test and grew slower as the test progressed. This phenomenon occurs because hard drives are fastest when they access data from the outermost tracks on its platters. Given a constant spindle speed (10,000 rpm, in the Velociraptor's case), the drive's read/write heads can simply cover a larger area in a shorter amount of time when positioned over the outer edges of the platter, resulting in better performance.

For optimal system performance, you need to place your OS and all of your most commonly used applications and files in the fastest areas on the drive. "

Here the outer tracks are 2X faster than the inner tracks:

For an SSD, you should follow Pjotr's recommendation. Likely, you will not experience any system lag afterwards.
... For an SSD, it makes little difference how you partition it, whether at the beginning or end of the drive, except that it is also recommended to leave an unpartitioned free space of about 10% in the SSD for wear-levelling purposes and the need to optimize the SSD ...

My recommendation was mostly geared towards a rotating HDD.

gparted can move your current Linux partition at the end of the drive to the beginning of the drive, if it matters. If you've got a lot of data to move it will take a while, but it will do it.
