Installing windows 7 64 bit from pendrive on 32 bit system

[comenium88]

Hello,
I have windows 7 32bit installed on my pc and i want to install windows 7 64 bit FROM USB PENDRIVE. how to do that?

 

[comenium88]

for those who think it is stupid question i give a hint... it is not.
Main problem is to make bootable pendrive. SYstem does NOT accept command bootsect.exe if the system i am using is 32 bit and i want to install 64 bit. That is why i am asking for some help
THX

Find a working Windows 7 PC
Go to control panel > back up and restore
Create system repair disc (on the top left)
Select the DVD RW drive or whatever you have a optical drive writer.
Create disc - after some time it will be ready.
Copy these files to a freshly formated USB stick

FORMAT THE USB DISK AS 'ntfs' or this does not work.

Assume that the flash drive is F and disk 1 in diskpart.
Create 2 folders on the flash drive - boot and sources

cd c:\recovery (could be c:\windows\system32\recovery)
dir /a:sh
cd YOUR_GUID_DIRECTORY (only subdirectory in c:\recovery)
dir /a:sh
xcopy /h boot.sdi F:\boot
xcopy /h Winre.wim F:\sources\boot.wim
cd c:\windows\boot\
xcopy /h dvd\pcat\bcd F:\boot
xcopy /h dvd\pcat\en-US\bootfix.bin F:\boot
xcopy /h pcat\bootmgr F:
attrib -r -s -h /s F:\*
diskpart
list disk
select disk 1
list partition
select partition 1
active
list partition
exit

Eject the flash drive and boot from it.

The above seems to work pretty well, i got it from a online search.
cd YOUR_GUID_DIRECTORY (only subdirectory in c:\recovery) < this bit is the hardest part, its in a really terrible location i found it by dir /s boot.sdi and it pops up.

regards

I have a silly question: have you tried to boot on it without running the bootsect.exe, just after the copying? It is said to be working on some computers.

I'm also reading that a 32 bit bootsect.exe (from a 32 bit installer, or Easybcd bin folder) also does the trick.

Create or download an iso format of W7 64 and use Windows Disc Image Burner
