sda is apparently your HD? It looks like it's allmost all formated as ext4 (linux) with Kali GNU/Linux 1.0.9, plus a small linux swap partition. And sdb is an 8GB (probably usb) drive with Ubuntu (syslinux) on it?
Do you have another HD with windows on it? Or if sda is your only HD, Windows would never install to an ext4 filesystem, it appears that if windows was ever on sda, it's gone now.
There's a chance you may be able to recover some of the files that used to be on the HD with a tool like testdisk or photorec, maybe even recover some partitions, but I'd guess that Kali overwrote a significant portion of Windows. - Unless there was a windows recovery partition at the start of the drive and only that was overwritten by Kali, then the "real" windows partition might be mostly there still.

For windows boot go trough sequence BIOS -> MBR (Master Boot Record on HDD) -> Partition Boot record -> BCD -> OS
GRUB usually installed in MBR, or in Partition boot, so You beed to restore MBR and partition boot record to eliminate GRUB and restore Windows boot.
Try this procedures to restore (https://neosmart.net/wiki/fix-mbr/#Fix_the_MBR_in_Windows_8_or_81)
If You alrerady tried "bootrec /FixBoot" ensure You do "bootrec /FixMbr"
Boot from the original installation DVD (or the recovery USB)
At the Welcome screen, click Repair your computer
Windows 8 Repair Your Computer Menu
Choose Troubleshoot
Choose Command Prompt
When the Command Prompt loads, type the following commands:
bootrec /FixMbr
bootrec /FixBoot
bootrec /ScanOs
bootrec /RebuildBcd
Press Enter after each command and wait for each operation to finish
Remove the DVD from the disk tray
Type exit
Hit Enter
Restart your computer and check if Windows 8/8.1 can now boot
If bootrec utility doesn’t fix your Windows 8/8.1, try following the next commands to fix the EFI bootloader of the Windows 8/8.1:
Boot from the installation DVD or the Windows 8 or Windows 8.1 recovery USB
Click Repair your computer
Choose Troubleshoot
Choose Command Prompt
Type these commands in order and hit Enter after each:
diskpart
sel disk 0
list vol
These commands will select the first disk of your computer and the list all the partitions available on that disk.
Check for the volume item that has the Fs column FAT32. The EFI partition must be formatted under FAT32.
If the volume number of EFI partition is “2”, type the following command:
sel vol 2
If the volume number is different than 2, replace “2” with the number available on your computer.
Assign a letter to this partition, a letter that is different that those already available on your computer, for example x:\. Type this command to assign the letter:
assign letter=x:
Wait for the success message to appear:
DiskPart successfully assigned the drive letter or mount point.
Type exit to quit the DiskPart utility:
exit
Type this command and replace x:\ with the letter you assigned earlier to the EFI partition:
cd /d x:\EFI\Microsoft\Boot\
Then type the bootrec command to repair the volume:
bootrec /fixboot
Now you need to backup the old BCD and recreate a new one. Type:
ren BCD BCD.backup
Type this command to recreate the BCD and replace the x:\ with the assigned letter earlier:
bcdboot c:\Windows /l en-us /s x: /f ALL
In above command, Windows is installed on c:\. If the drive letter where your Windows 8/8.1 is installed is different, replace c:\ with your drive letter.
Remove the DVD from the disk tray
Type exit
Restart your computer
"bootrec /FixMbr" and "bootrec /FixBoot" definitely replace GRUB by Windows boot records and enough for win 7 and older, but I dont hawe much expirience with EFI.
Upd.
I look at Your botinfo. Look like there no windows partition, ntfs or FAT32 on HDD (sda). You installed Kali on hdd and format it.
