NP530U4C not loading Windows 7

I have this model, I believe it's series 5. It came with Windows 8, I inserted a bootable usb to install Windows 7.

This laptop comes with 24gb ssd, and 500gb sata.

Before installing the windows, there were many partitions reserved for recovery or system. I deleted all, then created new. I ended with two disks, one is the 24gb ssd formated to ntfs and the second is empty sata.

I installed Windows 7 in both of them, but still have this problem after installing finished and restarted, the laptop doesn't load Windows 7. I changed things needed in bios but still the laptop doesn't load. It start with attempting to load an search, then a blue box with two options
Windows boot manager
And the 500 gb sata hdd

No one of them work however the windows 7 installed in both ssd and sata.

Any advice?

 

I suspect that the installer has put the boot files onto the ExpressCache. This trap has caught out many owners of the models with ExpressCache.

See here for how to fix the problem.

Thanks John
I tried different methods, nothing worked. Actually the 100mb system reserved partition doesn't have files to copy from.

Here are my partitions read to new install, all formatted. Disk 0 supposed to be ssd and Disk 1 normal sata.

 

Hi Sayyar,

This is now a few days old, but in case it is still relevant: On your model, downgrading to Win7 involves switching from UEFI mode to good old BIOS mode (so-called CSM), and converting your disk from GPT layout to MBR layout. That will wipe all disk content (including Recovery) but you say you already deleted everything.

It is covered in the guide that John linked ( here, post #40 in that thread) you but have to follow the EXACT steps in that guide, including the steps for converting your disk and changing BIOS settings BEFORE your start installing. Otherwise you will run into problems.

In addition that, on your model you ALSO have to work around the issue mentioned by John with Windows Setup being confused by the small ExpressCache SSD (so-called iSSD). You need to do one of the following:

1) Install from a DVD drive instead of a USB stick (an external USB DVD drive should work). This is by far the easiest.

2) Use one of the workarounds described here or here (posts #1 or #2 in the same thread as that install guide).

3) Leave the original MSR alone (the small Microsoft Reserved boot partition) and just format the Windows partition (don't delete it). But that is no longer an option when you have wiped your disk. Again, that is true for all who downgrade from Win8 and convert their disk from GPT to MBR.

For others about to embark on downgrading their Samsung laptop from Win8 to Win7, the post here sums it up.
