I have been researching the topic and am at a loss after around an hour of fruitless research. i recently upgraded from xp 32 bit to windows 7 32 bit. I want to upgrade to 64 bit so theres more RAM available and cannot find any information on doing it without discs that doesnt use USB or something. Got an external hard drive what the hell do I do? I downloaded the files but then couldn't open of course bc they were 64 bit files or whatnot.
Any help is much appreciated.
(my cpu is capable of running it)
To install Windows 7 using the Custom option and formatting the hard disk
To format your hard disk during Windows 7 installation, you'll need to start, or boot, your computer using the Windows 7 installation disc or USB flash drive.
Turn on your computer so that Windows starts normally, insert the Windows 7 installation disc or USB flash drive, and then shut down your computer.
Restart your computer.
Press any key when prompted, and then follow the instructions that appear.
On the Install Windows page, enter your language and other preferences, and then click Next.
If the Install Windows page doesn't appear, and you're not asked to press any key, you might need to change some system settings. To learn how to do this, see Start your computer from a Windows 7 installation disc or USB flash drive.
On the Please read the license terms page, if you accept the license terms, click I accept the license terms, and then click Next.
On the Which type of installation do you want? page, click Custom.
On the Where do you want to install Windows? page, click Drive options (advanced).
Click the partition that you want to change, click the formatting option you want to perform, and then follow the instructions.
When you've finished formatting, click Next.
Follow the instructions to finish installing Windows 7, which include naming your computer and setting up an initial user account.
dont have a cd drive. dont even have the disks i chose to purchase just the digital copy. must be a way around this
Nope -- going from a 32 bit system to 64 bit requires a clean installation since all of the files need to change -- so you'll need either a DVD or a bootable USB thumbdrive to copy the files to so that you can reformat the HDD and install the new OS.
2) mount the .iso file on a virtual cd/dvd drive; if you don't have anything like that, you can also use winrar to extract the iso
3) copy the files that are inside the iso image to your usb (the files take ~3,1gb)
4) once everything's on usb (let's say it's X , open command prompt (winkey+r, type in cmd press enter), type x:, cd boot, once you're located inside x:\boot, type bootsect /nt60 x: and hit enter, you should get the following message:
Target volumes will be updated with BOOTMGR compatible bootcode.
Bootcode was successfully updated on all targeted volumes.
incase it says 'access denied' then try bootsect /nt60 x: /force
congrats, your usb now contains bootable win7x64sp1 installation
one thing to note is some systems don't support booting from usb if:
a) your flash stick is not plugged exclusively straight at the back panel of your motherboard
b) you specifically set usb stick to be the 1st drive in boot order (some boards won't boot if you just pick to boot from stick via boot menu by pressing esc/f11/or whatever the boot menu key is for your motherboard)
