We will need some more information on your system here.
Unfortunately if this is occurring on the live USB you can't provide your inxi -Faz.
Maybe at least PC or laptop model, GPU used and if you use external monitors and how (HDMI?).
Finally, I remember a long thread on how to dual boot. Still doing that?
I remember your current Windows setup is BIOS/MBR, so this might play a role as well, meaning that Garuda should be installed in the same way. But I'm not an expert with that setup, since I'm on UEFI since many years.
Please also confirm if you have tried booting also with free drivers option and followed the instructions on disabling secure and fast boot in the BIOS, and SATA mode is set to AHCI.
I use a 4G USB key built with Rufus and the problem is the same with both my laptop and my PC.
On my laptop, I have W7 installed and on my PC, I tried it with only an empty SSD formatted installed (disconnected the two other bootable drives) and with those two drives connected with the same issue.
And what is a inxi-Faz anyway ?
I'll check for secure fast boot and come back. AHCI is on.
How old is this PC? When was the last time its BIOS was updated, and how much RAM does it have? Linux is not "intended for old or low-end computers" regardless of what you may have read or been told. That is a fallacy.
Garuda is an operating system focused on performance and that requires a minimal hardware profile. You can tell us what you have via the "inxi -Faz" terminal output. The required reading you skimmed over prior to posting has that information. Please read it.
Not the best choice, but you would not know that. The DD command, Etcher, or Ventoy are preferred over Rufus.
What is "both?" Please explain in detail.
Further, the fact "they" are both using BIOS/MBR concerns me. Garuda works and performs better with EFI/GPT (according to the specs). An older, low-end machine will probably not yield you optimal (or useable) performance on old equipment. A few Linux distributions are focused on older machines, but Garuda is a sportscar that does best on high octane fuel. The more modern the hardware, the better. (One caveat being well-configured Window Managers.)
@iBenny, we need you to help us help you, by re-reading and applying the "inxi -Faz" information. It's a total craps shoot without it.
When you'll be able to boot to a system, open a terminal and enter that inxi -Faz.
The output will provide your system specs, and should be copied in a post as text, with
before and after the text block, for formatting reasons.
Try with Etcher first, please.
For the laptop the issue could be with the GeForce GT 9600M which I think might not work with the latest proprietary drivers, so, more than ever, I think you should select free drivers at boot.
You have to understand that you are asking me to use a Linux command on a Windows system ! NOT very compatible. If the aim of this command is to give you the hardware profile of my pc then, maybe THIS and THIS should help, I hope.
Please note that I don't want to dual-boot with Windows but want to install it on a sole SSD.
My strategy is to disconnect all drives except for the SSD where GARUDA is to be installed and after installation, reconnect all disconnected drives and when I want to use GARUDA, I select it at boot time with the boot device selection. This provides peace of mind to assure Windows 10 does not mess up with the boot loaders and brake the dual boot functionality when it does updates.
Please do as instructed if you wish to receive help. Further, Garuda does not (officially) endorse dual-booting with another operating system. You will need to provide your own help.
More than one operating system on one computer can be problematic, regardless of what you call it. It is a good scheme, though, and hard to fault.
You'll probably do fine on the newer machine but please be sure your BIOS is updated on it since it is a new machine. Your laptop is a toss-up, though someone diligent enough may have decent results with it. Were it mine, I would definitely want to explore the low resources-consuming Window Managers, rather than the full Desktop Environments.
You need help with one computer at a time (one help thread at a time, too) though I suspect since you're having no luck booting either of them, that it is a bad ISO download, a bad USB key, or a faulty installation to USB.
Next which DE?
Write full ISO name, maybe you use a dev. Edition.
I dual boot on two laptops fine with M$, but if M$ destroy the boot part, I must fix it by myself.
Everything is possible in Linux, you must only know to help yourself, like booting from BIOS and so on.
I am afraid you are mistaken in your definition of dual booting, and @c00ter is more correct in this case.
While you may not be using a dedicated boot manager in your setup, you still plan on having more than one OS installed on your computer at a time. That qualifies as a multi-boot setup whether you agree or not.
Using separate drives for each OS is a better way of setting up a multi-boot system, but it still meets the definition of dual booting. While this setup is better than using a dedicated boot manager there is still the possibility of creating problems whenever one OS can see the other file system.
The only way this type of setup would not be considered a multi-boot system is if you physically disconnect all but one OS while the other is in operation. I use this type of setup with a 6 bay hot swap rack for my SSD's with different OS's installed on them. I only have one OS accessible at a time with this setup, so there is no possibility that one installation can view or modify files of the other drive. Even with this type of setup Windows can still interfere with devices on a hardware level and disable them for use in Linux.
Simply because you use your bios to select your OS at boot time (rather than a boot manager), does not mean you haven't met the definition of dual booting.
I still have such a huge box in beige to stand in the basement, it's time to bring it home again. Unfortunately only 4 hard drives to pull out.
Each slot has a real key in the rack. Safe is safe. In addition, I have the various hard drives at that time simply by self-built cables and toggle switch power to bypass the annoying in and out.
