Hello to everyone. Is this possible to resize somehow at the start of installation the 500 mb partition? I know I should use diskpart at the start of instalation, but I dont know how to proceed....
i dont think it is recovery partition, it is the small partition with no drive letter, where windows stores encryption stuff, and other windows features (bitlocker or something?) If you let windows format the drive it creates this small hidden partition, if you use diskpart from inside windows installation you can remove it, if you use the features, it puts those files on C drive, but if you disable those features, no need for that partition imo. fyi, it was ~250mb in 7, and i think now in 10, it is ~500mb
Afaik, windows will copy the winre.wim to it and therefore every windows install will create his own one. But take a look at murphy78's script, you'll find it informing at the least. The script is suited for multiboot installs.
Ok, informing it is, but unfortunately not for me. I wish to install win 7 first, and this script is for win 10. It was a nice thing to know, though..... Again, thanks to everyone tried to help.
It works with 7 too but you have to use a modded boot.wim from 8.x or 10 (you can take the whole 10 iso and instead of the install.wim from 10 you could use one from 7 or create a multiversion install.wim containing 7 and 10). The recovery partition part is not suported by murphy78 (it's not been made for 7) but the diskpart part from the script will always work.
If you're stuck on the old boot manager, you just need to log into win10 and do "bcdboot c:\windows" It should detect all installed OS version and update the bcd/bios/uefi for you.
I had tried bcdedit, standard, legacy, edits.... and it was just so simple... Thank you, it did the job!
