Replace x:\win81aio\win81\ with the your drive letter and path to the Windows 8.1 AIO Folder and also replace <Path_to_etfsboot.com_File>, <Path_to_efisys.bin_File>, <ISO_Label>, <AIO_Folder_Path> and <AIO_ISO_Filename> with your choice Microsoft uses -udfver 150, but i have used 200 Syntax : For BIOS Code: oscdimg.exe -b<Path_to_etfsboot.com_File> -h -u2 -m -o -l<ISO_Label> <AIO_Folder_Path> <AIO_ISO_Filename.iso> For UEFI Code: oscdimg.exe -bootdata:1pEF,e,b<Path_to_efisys.bin_File> -h -u2 -m -o -udfver200 -l<ISO_Label> <AIO_Folder_Path> <AIO_ISO_Filename.iso> For BIOS & UEFI Code: oscdimg.exe -bootdata:2#p0,e,b<Path_to_etfsboot.com_File>#pEF,e,b<Path_to_efisys.bin_File> -h -u2 -m -o -udfver200 -l<ISO_Label> <AIO_Folder_Path> <AIO_ISO_Filename.iso> Examples : For BIOS Code: oscdimg.exe -bx:\win81aio\win81\boot\etfsboot.com -h -u2 -m -o -lwin81aio x:\win81aio\win81\ x:\win81aio.iso For UEFI Code: oscdimg.exe -bootdata:1pEF,e,bx:\win81aio\win81\efi\microsoft\boot\efisys.bin -h -u2 -m -o -udfver200 -lwin81aio x:\win81aio\win81\ x:\win81aio.iso For BIOS & UEFI Code: oscdimg.exe -bootdata:2#p0,e,bx:\win81aio\win81\boot\etfsboot.com#pEF,e,bx:\win81aio\win81\efi\microsoft\boot\efisys.bin -h -u2 -m -o -udfver200 -lwin81aio x:\win81aio\win81\ x:\win81aio.iso
If you want further reduce the size of the os, then there is one option - The BOOT.WIM File and WINRE.WIM File (Inside the Install.WIM) Use ImageX.exe and export them with maximum compression, this will further reduce the overall size of the ISO by couple of MB's.
Boot.wim & Winre.wim are just in MB's and also there is only one boot.wim for whole os and also the winre.wim in install.wim in each index will be same and so it will minor change in size. but hope It will be make a overall size to fit the media your are trying to use.
first of all. What is the difference of: MBR partition scheme for BIOS or UEFI computers MBR partion scheme for UEFI computers GPT partition scheme for UEFI computers. Mister X. Did you try to burn your SuperAIO to your pendrive using another software like UltraIso, or is there still a limitation ?
Firstly I don't know if UltraISO can prepare a usb pendrive, I rather use Rufus, for me it does work. Secondly, you need FAT32 file system to format the pendrive in order to boot as UEFI for installing on a GPT disk, no problem with that unless you have a SuperAIO like mine (7.25 GB). Remember FAT32 has a 4 GB max size limit for a file. My SuperAIO has a install.wim file of 6.8 GB size. This is the main problem.
My usb pendrive is 8 GB and formated in FAT32. At this moment I am burning my AIO (6.75 GB) with UltraIso to my pendrive. And it seems working. How I sad, my usb pendrive is FAT32. But I created the AIO for BIOS, which needs that the usb pendrive is formated as NTFS. But Ileft it FAT32 and tested it on my Laptop, and worked. Booted from usb pendrive without issues. It may help you Mister X.
Very surprising for me your statement. Just confirm the size of install.wim for me please, just to know. However, I guess, not sure, the standard to prepare a USB pendrive for UEFI boot requires FAT32 forcefully.
Yes, I know. but I didn´t use for UEFI boot. I used FAT32 with BIOS,, instead of using NFTS, but also worked. The size of my install.wim is 6.71 GB.
mmm... Thar's interesting, I cannot explain how FAT32 can support a 6.71 GB file. I'm going to experiment
Hi MSMG. If i do the 8.1 by the Store method, i will get a iso of Pro 8.1 WMC, but with "instal.esd". Is that possible to convert-it in "instal.Wim ????? In that way, if i understood, this iso will work fine because it did become a "instal.wim" It seem to be the simpliest method for me. So, when 8 become a 8.1 by Store method, 8.1 for fine. But a iso of this wont be possible to add features, etc... because it created a "instal.esd" So that's why i sould convert-it to a "instal.wim" before a create a iso of 8.1 Tancrède
Yes you can convert install.esd to install.wim by installing the os on a virtualbox/vmware and the capture the image of the virtualbox/vmware hdd to install.wim and then setting the install.wim Name, Description to Windows 8.1 Pro With Media Center, Flag to ProfessionalWMC. But the easiest way is to just download the msdn windows 8.1 pro iso and change the edition to pro wmc and use your key.
May be he is burning the iso image to usb as a image and not copying the files in a normal manner. the usb is written in a raw image format i think.
MBR is general partition scheme used widely, GPT is used for larger harddrives (more than 2 TB) and nowdays people are using GPT for normal drives too.
Thanks MSMG. Indeed, it seem to be the simpliest way for me. Is the MSDN is a Retail version ????? If not, where i could find-it ????? And how can i change-it to WMC and use my key ?????? -- this tool: Windows Assessment and Deployment Kit, see on the first page of this subjet, will made the pro 8.1 a WMC, OK for that. But what is the method for use my key to activate 8.1 MSMG ????? Tancrède
