What is the boot order for a hard drive in the BIOS?
While reviewing my bios this evening, I observed that the SSD holding the Windows OS ranks fourth in the boot sequence. After adjusting its position to first, the system has booted more efficiently. It’s worth considering whether prioritizing one drive over others affects performance or introduces potential faults.
What PC? In most modern ones, only bootable drives with OS on it are displayed in the boot order, which isn't necessarily in the same connection sequence. Even if they aren't, the BIOS will scan all of them until it finds the first one that can boot. That might take a while, causing some delay.
Aorus z390 pro will share a picture soon about the bios boot settings. I agree with you. Initially, there were 5 hard drives listed, and the one with the OS was the 4th. It used to take 35 seconds to load into the Windows startup menu, but after rearranging it now it takes about half that time. I was concerned that keeping it in its original order or changing it might cause long-term issues, but I’m not sure if it really matters.
That’s my profile information there. At first I set it to number 5, then changed it to number one on slot 4. It was the default setting at the time. Does the sequence actually matter, or could an incorrect order cause issues?
It won’t cause any harm, though I faced issues when adjusting BIOS configurations. I lost the display from both internal graphics and the GPU. Still, I don’t understand what caused it. Do you know if your Windows was set up in legacy mode or UEFI? This is important when using Fast Boot. You can try disabling CSM, but but you shouldn’t make changes unless necessary. Please, don’t alter anything if you’re satisfied with how your PC functions. If you disable CSM, only bootable drives will be considered and startup times will decrease. Fast Boot can further reduce load times, though there are some drawbacks to consider. Check these links: https://www.technewstoday.com/fast-boot-gigabyte/ https://forums. With Fast Boot you should experience quicker boot times, but you might not be able to return to BIOS if your OS is in legacy mode. I wouldn’t risk your computer, so if everything remains unchanged for you, leave it as it is. If you decide to experiment with these settings, be aware of the potential risks. Nothing will break, but being unable to access BIOS again could cause significant trouble.
I’m not certain about the installation method since someone else handled it initially.
Leave the settings unchanged and ensure fast boot is turned off.
Regarding booting, I’ll wait until the hard drive starts with the OS first; sorry for the repeated questions, but this order won’t cause any issues either way?
Thanks for all the responses – really appreciate it.
It only indicates which drives to attempt booting from, starting with the first, then second, and so on. The system verifies each drive in sequence; if a drive is functional, it boots. If not, it proceeds to the next. This process doesn’t cause any damage.
In past configurations, boot order was often arranged so that a CD/DVD would boot first, followed by a hard drive. This ensured normal operation even without a CD/DVD, as the hard drive would boot automatically. However, with a bootable disc present, Windows installation or Linux installation could be initiated successfully.
