This thread already points in the right direction (see , , ). A few practical gotchas that aren’t fully explained in the replies will save time and frustration.

UEFI vs legacy firmware: modern machines often use UEFI and Secure Boot. For UEFI boot you generally need a 64-bit Windows 7 image and either enable the Compatibility Support Module (CSM)/Legacy mode or disable Secure Boot. UEFI installs normally expect a GPT disk and an EFI System Partition (FAT32). If your firmware is UEFI-only with Secure Boot locked on, Windows 7 setup will typically not boot until you change those settings.

The FAT32 4 GB limit: pure UEFI/FAT32 USB sticks cannot hold single files larger than 4 GB. If your ISO’s sources\install.wim is over 4 GB, split it rather than reformatting the USB. Example (run on a Windows host):

dism /Split-Image /ImageFile:C:\path\to\install.wim /SWMFile:D:\sources\install.swm /FileSize:4096

This produces install.swm parts that Windows Setup accepts.

Practical checklist and tips: use an 8 GB (or larger) USB, test the stick on a different PC, try the one-time boot menu (F12/ESC) before changing permanent boot order, and back up the USB (it will be erased). If you prefer a GUI tool that handles UEFI/MBR choices and common WIM issues, tools like Rufus automate much of this. Be cautious about flashing the BIOS — as warned, firmware updates carry real risk. If USB booting still fails, an inexpensive external USB DVD drive is the simplest fallback.

yeah, it is possible. i will assume pen drive is the same usb flash disk.
Install windows7 using USB
Another link, easier way

But, it might not work if you have an old computer with old version of BIOS. if it doesnt let you boot from USB, you have to update your BIOS(google it) or find DVD Drive.(i suggest to use DVD drive, bc updating bios is not easy, i have never tried)

BTW, i found the links using google.com, so, if it is possible, google before asking ;)

try to see if in bios you have the option to boot from usb.

format your usb pendrive with ntfs

create partion on your pendrive with disk part and mark it as active

update you pendrive with bootmgr code

lastly copy all the content of the win7 dvd to your pendrive

Yes, It is possible to boot from pendrive.
First, install windows on your pendrive which is bootable, then set the priority of booting option to pendrive, and the rest, u know.!
