Hi there,

I posted this in another part of the forum, and it's been suggested that I'd be better off asking here.

I'd be very grateful for advice on this. If I'm asking in the wrong place I'd be very grateful for suggestions on where else to ask.

I've just bought a new Lenovo H50 desktop. It comes with a 1TB hard drive, and Windows 10 was pre-installed.

I thought from past experience (just as a home user who has had a series of desktops over the years) that I should partition the disk: maybe 200GB for Windows and Program Files and the rest for data. When I looked at it via Manage, though, it seems to have been partitioned already. It has (in this order, from the left to the right):

- a 260MB EFI System Partition (I don't know what this is)
- 899GB+ Windows C:
- 1000MB Recovery Partition
- 30GB Recovery Partition, and
- 500MB OEM Partition.

I don't know what the EFI, two recovery partitions and/or OEM partition are for, and I don't know what might be on them. Googling hasn't helped, and I can't find a manual that might help to explain it.

I'm really just wondering whether it would be okay/a good idea for me to delete any of those partitions, or whether I should just leave them alone. The only drive letter that shows up in Explorer is C:.

I haven't had a new PC since 2008 (XP) and would like to set this one up optimally (partitioning if appropriate, reliable backup/restore system) but things have moved on so much since 2008 that I'm struggling to work out the best way forward.

Should I just transfer all my data (documents, photos, music etc) to folders on the C:, or would it be best to make a new partition? If so, should I leave all the existing ones alone?

Many thanks for any advice,

Shirl

Every vendor do their own thing and reserve partitions for their own purposes, as such unless you know EXACTLY what you are doing, I would leave them well alone, they are not taking that much space anyways.

So, the only thing you want to fine-tune is your 900GB C:. I too, like my OS+App on C: and everything else on D:. If that's the case all you have to do is to go into Disk Manager, tell Windows to SHRINK C: into 200GB you say. at the end of that operation, Windows should open up a 700GB UNALLOCATED SPACE. Take all of that space, and Create a New Partition on it and name it D:. That's it.
