I made things worse with a Windows 7 64 bit installation

Ok before when booting up the computer I am using to install Windows 7 64 bit to a certain hard drive well it showed all 3 drives but now it is only showing 2. I have a 3 TB hard drive that I know is in working order and I am just wanting to install Windows 7 64 bit to it and then place it in another pc. I do not care if I don't get the whole 3 TB as I can't as neither the computer I am using to format this drive nor the computer it is going into has a UEFI BIOS. So right now this 3 TB hard drive that used to show up suddenly doesn't after I removed the way it was formatted. It was not going to take Windows 7 64 bit onto it in the way it was formatted. Anyway I am beyond frustrated. I am ticked right off. Please help. I just want to get this into a 2.2 TB or whatever format and install Windows 7 64 bit to it. :S

Update: Solved the issue of being able to see it on this pc and format it so it would take the OS .... as I got the help needed from this ---> http://www.tomshardware.com/forum/281410-32-computer-find-hard-drive-format-drive

Update #2: I transferred the drive over to the other pc after installing the OS on it and I got an MBR error.

HELP!

Hi!
Windows does NOT support hard drives with more than 3TB using MBR, you have to use the GPT model and install it using the UEFI version of the windows installer, I am not exactly sure, but i think it doesnt support GPT on non UEFI installations, is your new installation UEFI?

Kitstainedheart I did not use GPT because you can't install Windows 64 bit OS to it if you choose that. I got the OS installed but like I said when I hooked it up to the other pc it came up with an MBR error. You are supposed to be able to use this as a hard drive with an OS on it the way I did I thought and yet it didn't work. :S

actually you can install it with GPT, but its kinda "secretive", you need to enter the UEFI setup and select the advanced partitioning, it automatically makes a GPT partition for you, HOWEVER, for some reason, the GPT partition format it creates is different than the ones you get from most linux distros and such, if you format with GParted, windows will not allow the installation to proceed... (at least for me LOL) o-O;

I think the answer here is to smash it with a hammer.

LOL take it easy~~
dont smash it with a hammer~~
(use a gun, its less effort XD)

Well this just all seems so ridiculous. I mean I can't even get it into a state where it will just use 2 TB/1.99 TB and run on the other pc. I just don't get it. :S Oh and for the record I just tried to format an old 250 GB Western Digital SATA hard drive I had laying around and well the pc would go black screen with it attached when the pc was almost into Windows 7 booting off another drive. The 250 GB Western Digital SATA hard drive is broken in some fashion I believe. I can hear it spin but yeah she is dead. With all this said I am now wishing I never sold hard drive that Western Digital 1 TB that Western Digital gave me from a Western Digital 640 GB RMA as I would have had a 1 TB to work with to put in and the OS would have installed just fine. Yeah I got good money for the drive but now I am stuck with a 3 TB hard drive in working condition that I can't get an OS installed to and now the second gaming machine is not up and running. :S Oh and this all happened nicely on a weekend where my son was actually interested in gaming with me for crying out loud which is rare!

Dx that sucks....
well, uhh this is how i installed MY version here, and it works fine 3TB AND Windows 10(Works with 8.1 too, you have to check for 7);

soo, i get ISO, and use this lil app called YUMI to put the ISO in a usb flash drive or even a USB hard-drive (you can probably put it into an "actual" HD too);
from there, i restart the pc and choose the UEFI boot for the drive, it then enters the windows installation, i select the custom partitioning, and delete everything and recreate the partitions, and click install~~

and that sucks! i am sorry for you and your son! Dx

kitstainedheart it says that YUMI works with Windows 7 so now I got to go get the only USB flash drive I have in the house (pathetic that I do not have more but it is what it is) and dump the Xbox 360 stuff on it to my hard drive. Eh now reading the USB flash drive it shows no Xbox 360 stuff so now I am like wth? Uh this says it is going to do a FAT 32 format and I am trying to install 64 bit OS so uh is this not going to fail? Also are you saying you put an ISO of the OS on the USB flash drive? If so I don't have an ISO of the OS but trying to create one now.

YUMI formats your flash drive Dx
annd i wasnt sure about the GPT part of windows 7, i know YUMI does support it~~
and yes its FAT32, dont worry! its because of bootable issues with other file formats (because YUMI supports LINUX too);
go for FAT32, if it FAILS TO ADD THE ISO, then format as NTFS (wont happen since most ISOs are like 4-5gb);

*EDIT: to format as NTFS: format with windows explorer (right click on drive, and format); and then in YUMI uncheck the format part;

Just great. I can't see the Xbox 360 files but they are there and amount to almost 16 GB and I am not sure I want to erase them so I think using the flash drive is out of the question. :S

hmm......why dont you try installing a newer version of windows to see if it fixes it? o-o
like 8 or 10?

kitstainedheart a newer OS won't help. I am going to go and try to see if I can find 16 GB of room on my Xbox 360 by deleting some stuff. Eh anyway someone elsewhere said I should install the Windows 64 bit OS to the 3 TB hard drive like I did before but when the MBR comes up just pop in the dvd and boot with it to repair the OS. Thing is I bet you went it asks me to do that it will ask for a floppy disk or USB memory stick. In fact with MBR error before it was actually of all things asking for a floppy disk. :S

Update: I found what appears to be a working 160 or 120 GB Western Digital hard drive. I had to pull it from an older build but hey it was in an old dual core rig with a 9800 GT and I haven't done much with that in awhile so yeah. Anyway I am going to pair the old hard drive with the 3 TB as I think clearly that is just the simpler route to go.

Update 2: I found out that the CD/DVD drive I was trying to use last night to install to the 3 TB hard drive was dead in terms of it reading anything. So that definitely made matters worse. I ended up swapping in a media drive from my pc into my son's pc.
