Virtualbox - Windows 7 x64 slow loading

after moving *.vdi files to my new notebook I noticed that it takes long time to boot WIndows 7 x64(on 2 different VM's) on Windows 8.1 x64. That VM's worked perfectly on my home PC on Windows 7 X64 host(another version of VirtualBox). How I can fix this?

Here are the specs:

VirtualBox 4.3.20 r96997

Guest Windows 7 x64 specs
CPU: 4 core 100%
Ram: 8GB
Video memory: 256mb
3D accelaration: on
2D accelaration: on
Enable I/O APIC: on
Enable VT-x/AMD-V: on
Enable Nested Paging: on
Enable PAE/NX: off
Enable EFI: off

My notebook properties:
Asus G751
CPU: i7 4710HQ
Ram: 24GB DDR3L
GPU: GTX860m
HDD: 2 x 1TB 5400rpm
Host OS: Windows 8.1 x64

P.S. I moved *.vdi files to my notebook and then just created Vms with the same names as on my PC and with the same settings for everything(CPU, RAM, GPU, e.t.c.).

After you moved the files did you make sure the files were not fragmented? – Ramhound – 2015-02-04T15:48:28.020

No, how can I check that? – IKM2007 – 2015-02-04T15:49:34.523

To me it looks like you are currently processor bound (equal or more cores than the host assigned to the guests), try assigning less cores to the VM. Also, when you create a brand new Win7 VM on the notebook, does it run as expected? What all have you attempted already in trying to rectify this? – Ƭᴇcʜιᴇ007 – 2015-02-04T15:58:07.030

capture a boot trace with xbootmgr: http://pastebin.com/CYGqRZXE

My desktop HDD also 5400rpm and by "slow" I mean that windows 7 logo animation proceeded very slow(about 10-15 sec), not in normal speed. On my PC its running smoothly. – IKM2007 – 2015-02-04T15:47:22.537

In such case check if you install proper videdrivers on host OS. And activate videoacceleration for virtual machine – Romeo Ninov – 2015-02-04T15:53:06.047
