    My current OS is Windows 7 32bit. I need to do a clean install of Windows 10 64bit. For now, I don't have a DVD writer or a USB flash drive bigger than 4GB.

    What I have,
    4GB USB Flash drive
    a DVD ROM
    1 additional internal HDD [with some free space (2 partitions)]
    1 external USB HDD (backup) with free space.

    What are my best options?

    Create ISO from ESD, click on ISO, then mount, reboot:D

    What is your current windows? When already 10 then you can do a reset.

    Go to: settings app > update and security > recovery > reset this pc.

    If your rig's recent you can create a first primary bootable 8GB or 16GB FAT32 partition and boot from it (you only need 5GB for windows' setup files, the rest leave it for just in case and maybe some drivers) on the USB drive, create a secondary partition and format as NTFS like always.
    BACKUP FIRST (you have to empty the USB external drive)

    Doesn't work on all computers, unless recent (uefi boot) but it's the fastest way to get it done,

    Well, yes, but the OP's stipulation, as stated in the title, is for a clean install to be performed without a DVD or a USB stick. In the post it's stated that they don't have a USB stick that's bigger than 4GB (which I take to mean that smaller ones are lying around) but OP does have an external hard drive with stuff already on it. Most UEFI implementations won't let you boot directly off an NTFS drive (patents, I assume), hence the stuff with a flash drive to be able to get the UEFI to read from that hard drive. This way, nothing gets lost on the external drive (well, unless a mistake is made during setup). The only thing I don't know is if OP is doing an EFI install.

    Yeah the 4GB limit i did not take in consideration.

    But he simply could do a reset (when already on 10) or open the iso on the running desktop and upgrade with the option to take no files or settings to the new install (can't provide the correct text or sshot atm, sorry).

    Do you have a 512+ MB USB drive you can make bootable, or something like a bootable Windows 8 DVD? If so, you could boot to WinPE and apply the image manually.

    I have 4GB and 1GB flash drives. I also have Windows 7 DVD. So how can I boot to WinPE and apply the image manually?

    I've made an empty iso (all unneeded files deleted, result = 41MB), when you want you can extract the empty iso (based on 14393 Pro x64 en-US) to the FAT32 formatted usb thumbdrive and ad your own boot.wim and install.esd and it will fit on a 4GB usb drive. If you are interested in the empty iso, send me a pm and i'll provide you a downloadlink. If you don't trust it (OR want the iso in another language) you can recreate your own empty iso by deleting all the files from a clean iso with the exeption of the files shown in my empty iso.

    The iso i'll send you doesn't contain the boot.wim and install.esd.
    The iso size with boot.wim and install.esd files is 2.90 GB (3,116,924,928 bytes) 14393 Pro x64 en-US.

    The iso will only be able to boot (UEFI & BIOS), not upgrade.

    @cdavisdeco

    Please search before post - it supports legacy installation too.

    Option 1: Use dism /apply-image or imagex /apply (and easybcd to configure the dual boot)

    Option 2: If you want to waste some more time with a traditional setup, use easybcd to add the iso image to your bootloader and choose the setup menu item during the 1st reboot.

    No need to mess with setup media and other MS or external programs

    What are these "unneeded files" you're referring? And why does this ISO can't be used to upgrade?

    Sorry. But I read the guide for new installation. There are few things not quite clear to me. Do I need another windows installation to run the WintoHDD with the source ISO?

    Can I run easybcd from,

    A) secondary/external HDD

    OR

    B) a USB flash drive and chose the Windows ISO from the secondary/external HDD

    to install Windows to the primary HDD?

    Use easybcd to add a boot item to your current OS, the additional boot item would be the iso image.

    About the usb flashdrive isn't that the opposite of what you asked? If You have an USB pendrive just use it normally.
