    Hello,
    I am the owner of the Dell Inspion 7548 laptop with the win 10 system installed. I decided to change the HDD to SSD. I did not want to "rebuild" the system, so I decided to clone the system partition (C: /) using EASEUS Partition Manager Free. The copying process with the selected "optimize to SSD" option ran smoothly. He then replaced his old drive with a new SSD and started up the computer. After booting up, a message appeared about the lack of a bootable device. BIOS detects the drive. How should I configure BIOS / UEIF? Should the disk be prepared in some way for the system to boot from it? Thank you in advance for your help.

    The HDD Clone program will solve your problem, but you will not be able to clone one partition because the system creates one or more partitions at the beginning of the disk (depending on the system), which are relatively small but necessary for booting the system. So use the full disk cloning option if possible.

    So it is not possible to copy part of a partition (e.g. omitting one)? Should the system be put up from scratch? Failed to clone all partitions because of a smaller target disk.

    Maybe it is possible to add the missing data that are needed for booting?

    After all, you can choose which partitions should be cloned and resize them.

    I know that and I did it - I only cloned the partition on which the system was installed, but in this configuration, after connecting an SSD with this one partition, the disk is not bootable. The Taliban's statement shows that in order for the system to start properly after cloning, all partitions must be copied from the HDD. If I have misunderstood, I am asking for a correction.

    What about the hidden partitions the installer creates? This is where the system starts. Check "Disk Management" to find out what and how many partitions you have.

    The "C" partition alone is not enough. Give a screenshot of the disk management of both disks.

    Which partitions should I clone? Are some of them not Dell recovery partitions?

    SSD 240 GB and HDD 1TB. I am in the process of cloning 3 system partitions according to the comments of my colleagues above.

    Yes, in my opinion PBR Image and WINRETOOLS ;-)

    Subject solved. Using AOMEI Backupper Professional, using the available system cloning option (only available in the PRO version), I made a copy of the partitions that are needed to boot the system (3 partitions). The program finds and selects the necessary partitions itself. The whole process is very simple. Then disconnect the HDD and plug in the SSD in its place.

    Thanks to everyone for your help.

Topic summary

✨ The discussion revolves around a Dell Inspiron 7548 user attempting to clone their HDD to an SSD using EASEUS Partition Manager. After cloning the system partition with the "optimize to SSD" option, the user encountered a "lack of a bootable device" error upon booting from the new SSD. Responses highlighted the necessity of cloning all relevant partitions, including hidden ones essential for booting, rather than just the system partition. The user later resolved the issue by using AOMEI Backupper Professional, which automatically identified and cloned the necessary partitions for booting, allowing successful startup after replacing the HDD with the SSD.

FAQ

TL;DR: Cloning only C: leaves your SSD unbootable. You need 3 partitions; "The first 3 partition" fixes it. Use a System/Disk Clone that copies EFI, MSR, and OS, then boot the SSD alone. [Elektroda, Talibanczyk, post #17423983]

Why it matters: This FAQ helps Dell Inspiron 7548/Windows 10 users fix "No bootable device" after cloning an HDD to SSD without reinstalling Windows.

  • UEFI Windows 10 needs the EFI System Partition (FAT32), MSR, and Windows partition; typical sizes: ESP 100 MB, MSR 16 MB. [Microsoft, "UEFI/GPT-based hard drive partition layout"]
  • In this case, cloning the required three partitions produced a bootable SSD. [Elektroda, Sangnoir, post #17425063]
  • Moving from 1 TB to 240 GB requires shrinking C: so used size fits the SSD. [Microsoft, "Shrink a basic volume"]
  • AOMEI Backupper Professional "System Clone" auto-selected the needed partitions and solved the boot issue. [Elektroda, Sangnoir, post #17425063]
  • First boot with only the SSD connected to avoid bootloader confusion from the old HDD. [Elektroda, Sangnoir, post #17425063]

Why won’t my cloned SSD boot after moving Windows 10 from HDD on a Dell Inspiron 7548?

Cloning only C: leaves out the EFI and MSR partitions required for UEFI boot. Use a System or Disk Clone that includes those partitions. In this case, AOMEI Backupper Professional’s System Clone auto-selected three required partitions. After cloning, power down, remove the HDD, install the SSD, and boot. This resolved the “No bootable device” error on a Dell Inspiron 7548. The BIOS detected the drive, so the issue was partition selection. [Elektroda, Sangnoir, post #17425063]

Which exact partitions must I clone for Windows 10 UEFI boot?

UEFI Windows uses the EFI System Partition (ESP, FAT32), the Microsoft Reserved (MSR), and the Windows partition. A Recovery partition is optional for boot. Typical sizes are ESP 100 MB and MSR 16 MB. Cloning ESP, MSR, and the OS partition yields a bootable system on UEFI/GPT. [Microsoft, "UEFI/GPT-based hard drive partition layout"]

Can I clone only C: and still boot?

No. “The "C" partition alone is not enough.” Cloning only C: omits the EFI partition that holds boot files and the MSR. The system will show “No bootable device” even if the SSD is detected in BIOS. Clone the boot-related partitions together. [Elektroda, nici, post #17423787]

How do I shrink my Windows 10 partition so the data fits a smaller SSD?

Shrink C: so the used space fits your SSD before cloning. 1. Open Disk Management, right‑click C:, select Shrink Volume. 2. Enter the amount to shrink so total size is below the SSD’s capacity. 3. Apply, then proceed with your clone to the SSD. This reduces the partition size safely and lets you migrate to a smaller target. [Microsoft, "Shrink a basic volume"]

What’s the simplest way to clone to a bootable SSD?

Use a tool’s System Clone so it auto-selects the boot partitions. In this case, AOMEI Backupper Professional selected three required partitions automatically. It cloned from a 1 TB HDD to a 240 GB SSD. After cloning, disconnect the HDD and install the SSD in its place. The laptop then booted Windows 10. [Elektroda, Sangnoir, post #17425063]

Do I need to change BIOS/UEFI settings after cloning?

No BIOS change was required in the solved case. The failure came from missing boot partitions, not firmware configuration. Boot the first time with only the SSD connected to avoid bootloader confusion. After verifying, reconnect the old HDD for storage if desired. [Elektroda, Sangnoir, post #17425063]

Which partitions are Dell recovery on the Inspiron 7548?

PBR Image and WINRETOOLS are Dell recovery partitions. They provide OEM recovery tools or images and are separate from the boot-critical partitions. [Elektroda, leonov, post #17424222]

Are recovery partitions required for boot?

No. Windows boots from the ESP, MSR, and the Windows partition on UEFI/GPT systems. Recovery partitions host Windows RE tools and factory images for repair. They are not required for normal boot. [Microsoft, "UEFI/GPT-based hard drive partition layout"]

Is the “Optimize for SSD” option enough to make a cloned partition bootable?

No. That option aligns partitions for SSD performance, but it does not create the EFI boot partition or boot entries. A partition-only clone with SSD optimization remained unbootable in this case. [Elektroda, Sangnoir, post #17423485]

What does “No bootable device” after cloning actually indicate?

It means the firmware did not find a valid bootloader on the disk. Here, the BIOS detected the SSD, yet Windows did not start. The cause was missing boot partitions rather than a hardware fault. [Elektroda, Sangnoir, post #17423485]

Should I use Disk Clone or Partition Clone when migrating Windows?

Use Disk Clone or System Clone that copies all boot-related partitions. Partition cloning only C: will not create a bootable SSD. Full disk or system cloning avoids missing hidden boot partitions at the start of the drive. [Elektroda, Talibanczyk, post #17423538]

How do I check which partitions I have before cloning?

Open Windows Disk Management to review all partitions, including hidden ones. Note the EFI System Partition, MSR, OS partition, and any recovery partitions. This helps you select the correct items in your cloning tool. [Elektroda, leonov, post #17423772]

Can I add missing boot data without recloning?

Yes. If an EFI System Partition exists, use bcdboot to write Windows boot files. Example: bcdboot C:\Windows /s S: /f UEFI, where S: is the EFI partition. This rebuilds UEFI boot files on the cloned SSD. [Microsoft, "BCDBoot Command-Line Options"]
