According to Google search results, there are mainly 2 contexts for the question: one is how to make another hard drive or SSD bootable (and how to deal with cloned drive won't boot issue); the other is how to make a bootable USB drive.
Approach 2. Boot Windows 10 from USB flash drive (at startup)
They are 2 completely different questions, but both will be answered in this article.
- To put it simply:. ◇ To make a hard drive bootable: It is usually achieved by cloning OS & data to another hard drive.
- If you've tried cloning and the cloned drive won't boot, this may be due to wrong boot mode, wrong boot option, incompatible partition style, or corrupted boot files.
- You'd better use professional cloning software to minimize errors.
- ◇ To make a bootable USB drive: Windows does provide some tools to make bootable USBs, which differ somewhat in functionality.
Note: Any USB storage device larger than eight gigabytes will work, including external hard drives, external solid-state drives, and any kind of SD card that will plug into your computer.
But generally the purpose of a bootable USB is to start a computer for further repair or installation.
Why cloned HDD or SSD won’t boot and how to solve it
To make a drive bootable in Windows 10, clone is the easiest way, it's able to copy all the necessary boot files required by Windows to run.
However, since Windows itself does not have cloning capabilities, you can only use third-party disk cloning software. There is a large amount of clone software on the market, how to choose a reliable kind? You can refer to the following standards:.
Professional and safe: The cloning software is able to make disk bootable in Windows 11/10/8/7/XP/Vista after cloning, and won’t mix up your disk.
Easy to use: Clear interface and user-friendly design are important for cloning software.
Strong compatibility: Good clone software should be compatible with different versions of the Windows system, different sizes of drives, as well as diffent partition styles (MBR/GPT).
Customized options: Besides the basic standards, a great clone software also provides users useful features to adjust and optimize cloning results, such as sector by sector clone, SSD alignment, resize partition, allocation of unused space, etc.
Warning: The Media Creation Tool will completely wipe any USB drive you choose to use. Back up any files you want to save before proceeding.
Based on these criteria, I recommend you AOMEI Backupper Professional, which combines comprehensive and useful features in the simplest interface and process, allowing even non-tech-savvy users to complete cloning operations with a high success rate.
First of all, its default intelligent mode will copy only used sectors.
This makes cloning between disks of different sizes easy, solving the problem of cloning larger disks to smaller ones for many users.
And for users who want to clone hard drive to larger drive without leaving unallocated spaceby, its Edit Partition feature comes in handy. In terms of compatibility, AOMEI Backupper Pro works on all PCs running Windows OS, and allows you to clone both MBR and GPT system/data disks, as long as they can be detected by Windows.
In addition, it includes a Create Bootable Media tool, which can be used to boot problematic Windows computer and perform backup, restore, etc.
