Hello everyone, I have again dealt with the topic of dual boot Win7 (without CSM)/Win10. Now I have a solution that is satisfactory for me and is relatively simple, provided you use an additional program Emergency Boot Kit! Addendum: Of course you also need WIN10 Bootstick(should be clear) and the 2 programs EasyUEFIV5.5 freetrail and refind-bin-0.14.2.zip 1. prepare a bootstick with Emergency Boot Kit pro(EMBKp)(Wonderful work on you guys!) 2. prepare bootstick for WIN7 UEfi (for example with FlashbootPro which is highly recommended,awesome Tool) 3. run Win7 Installtion Bootstick and let the program create partitions automatically.(You are still in Win7 installation mode) 4. delete the primary partition for WIN7 again (You are still in Win7 installation mode) 5. now create a 500MB partition (later for EFi PArtition WIn10) without formatting(You are still in Win7 installation mode) 6. halve the remaining hard disk capacity as you want WIN7 and WIn10(You are still in Win7 installation mode) 7. have Win7 installed in the corresponding partition (previously halved)(You are still in Win7 installation mode) 8. boot EMBKp and format the 500MB partition with VFAT 9.Change GUID to EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 (basic data partition) with EMBKp on the 100MB partition(EFI) 10. Change GUID to C12A7328-F81F-11D2-BA4B-00A0C93EC93B with EMBKp on the 500MB PArtition 11. now perform Win10 bootstick installation on the halved remaining partition and wait for the complete installation automatically 12. now you can only boot Win10. 13. install EasyUEFIV5.5 freetrail on WIn10 and unpack refind-bin-0.14.2.zip on Win10 14. use EasyUEFIV5.5 to install refind on the 500MB partition and set refind to first place in the boot order. 15. ready!!!! Now reboot and you can directly select which operating system you want to boot. This method works perfectly and has been tested several times by! 16. another note on activating Win7: Use EMBKp to change the GUID of the 100MB partition back to EFI partition (500MB basic partition again) then activate. Then reset everything again steps 9 and 10!!! After that everything is ready and rEFInd finds the patched bootloader to load Win7! 17. activate WIN10 normally WELL DONE!!! This may read and seem a bit complicated but just follow the plan and WIN7(without CSM)/win10 is no longer a problem on a hard disk!!!! Conclusion: With Refind, it is always possible to choose between operating systems when starting the computer. Refind also automatically hangs on the last choice of operating system, so you don't have to choose and refind automatically starts the selected operating system after a few seconds waiting time. If you do want to start the other operating system, you always have enough time to react!
W7 UEFI GPU not working MSI AMD B650m UEFI mobo, Ryzen 5 7600x cpu, RX560 gpu I dual boot w10/w7 on seperate m.2 drives. Have installed W7 using dism and flashboot bootmgfw. Have all drivers installed Ok except for wifi. The RX560 gpu works Ok on W10 but not on W7 problem is that even tho the drivers for the radeon gpu are installed without error in device manager they do not appear to be communicating with the system. No graphic apps detect the gpu nor does DirectX. Is this because of Fastboot Int10 fix or just a feature of this gpu, would a different gpu work ? any info appreciated.
Hi, WIN7 UEFI actually works normally with FlashbootPro without any other tools!!! Why you use dism, I don't know1 The driver thing with WIN7 UEFi is strange. Int10 patch should have no influence, because it is generally valid at startup. In desktop mode the AMD driver will be active again. Why this driver does not work is a good question. Did you install the AMD driver after you installed WIN7 Uefi!!!? AMD also had 2 different driver packages, didn't they?
Thanks for reply, Tried flashboot with usb but the stick would not even boot. The patch would not install either. I used an install wim with the basic usb3 drivers ect and used dism to install it to a prepared system partition a lot quicker than fafing about with a usb/dvd, takes less than a minute, build/populate the Efi partition and its good to go. Radeon drivers were installed using the latest W7 Adrenalin 22.6.21 install software without errors after W7 was up and running. (have tried older drivers but same problem) There was an earlier thread where someone had a similar problem with flashboot and the RX550 gpu not being detected but I can find little else. W7 is starting with the vgasave driver and not with the RX560 drivers. If you disable the vgasave driver W7 hangs at the startup logo so I'm sure the flashboot kernal patch is involved somehow or a mismatch with this particular Gpu series. I would like to use the Amd 6000 series which I believe is the last one that had W7 drivers but will it work ???
Motherboard MSI mag B650m Mortar (MS-7D-76) V2 Bios AMD A.C0 AGESA ComboAM5PI 1.1.0.2b 04/03/2024 Have tried booting with UefiSeven but W7 hangs on the startup logo Flashboot seems to be the only fix that works with this Mobo. Have tried booting with the amdwddmg.sys kernal driver in startup boot/system mode instead of manual with no change. There is a radeon popup every 5 min warning of OpenGL omission otherwise no errors reported at all. Does anyone know of an alternate GPU Nvida, Geforce etc that may work ?
Flashboot pro works without problems! It has always worked. I am sure of it. Use Flashbootpro and it works without problems!
Flashboot pro does work.I can boot Win7 in UEFI mode no problems, except, there is no Aero effects. My AMD Radeon 6900xt is recognized, but I cannot get Aero to work.
Interesting Bios options, but it's not clear if CSM is disabled. you may be booting in UEFI mode with CSM also enabled you may check if CSM is enabled while booting under UEFI by booting windows 7 without UefiSeven of FlashBoot windows 7 with latest available updates are able to boot under UEFI with CSM enabled just fine without any external help if CSM is disabled, windows 7 will never pass the welcoming logo screen. in that case, CSM is disabled. pushing the power button should gracefully shutdown windows 7. Edit: did you manage to find signed drivers for windows 7 for both RX 6900 XT & UHD 630 ? could you possibly share the results of dxdiag for RX 6900 XT & UHD 630 ?
Update- Initial setup had the Ryzen 7600x IGU disabled and just Uefi boot. have discovered that if CSM and the IGU are enabled in bios that the RX560 Gpu is fully operational in W7. If disabled in bios then Amd RX drivers are installed but do not work. MSI Bios boot W7 with Fastboot efi patch Uefi or CSM with IGU enabled amd drivers loaded and working Uefi or CSM with IGU disabled amd drivers loaded but not working The Amd HDMIaudio driver is only loaded when IGU is enabled.(same for w10) May need to disable basic vga driver in device manager. Am intrigued as to why this should be, any ideas anyone ?
you only need uefi7 or flashboot when CSM is either disabled or not available UEFI boot with CSM enabled works just fine on windows 7 with recent updates without any external help
Hi primeExpert-Software, I have always used your tool Flashboot pro to install Windows 7 UEfi. It works great!!! Unfortunately the installation with USB keyboard never worked/the mouse worked anyway!!! I have now found out that the USB drivers from Simplix WinISO USB Boot stick work. Something goes wrong or doesn't work when mounting with your Flashboot Pro tool! I would like to know how to solve the problem now!??? Greetz
FWIW, natively UEFI (CSM on) booting a freshly build SiMPLiX AiO ISO on a i3-12100 along with a GTX 1050 works just fine. GPU drivers install and work just fine booting with Flashboot Pro 3.3n to UEFI (CSM off) on this very same system results in an error (Code 12) on the GPU driver for UEFI Class3 booting, I have to use RefindPlus for loading Flashboot Pro, otherwise I get a GOP error. Edit: the reason for this problem explained 3 years ago in this very thread page #4 possible suggested solutions may be:
