Why doesn't my bootloader load my kernel?

I have coded the minimal realization of OS booting on assembly:

    [BITS 16]
[ORG 0x7C00]
start:
mov ax, cs 
mov ds, ax  
mov ss, ax 
mov sp, start 

mov ax, 0x1100
mov es, ax
mov bx, 0x0000
mov dl, 1 
mov dh, 0 
mov ch, 0 
mov cl, 2 
mov al, 1 
mov ah, 0x02 
int 0x13 

mov ax, 0x1200
mov es, ax
mov bx, 0x0000
mov dl, 1
mov dh, 0
mov ch, 0
mov cl, 3
mov al, 1
mov ah, 0x02
int 0x13


cli
lgdt [gdt_info]
in al, 0x92
or al, 2
out 0x92, al    
mov eax, cr0
or al, 1
mov cr0, eax
jmp 0x8:protected_mode 
gdt:
db 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00
;base=0, size=4Gb, P=1, DPL=0, S=1(user),
;Type=1(code), Access=00A, G=1, B=32bit
db 0xff, 0xff, 0x00, 0x00, 0x00, 0x9A, 0xCF, 0x00
;base=0, size=4Gb, P=1, DPL=0, S=1(user),
;Type=0(data), Access=0W0, G=1, B=32bit
db 0xff, 0xff, 0x00, 0x00, 0x00, 0x92, 0xCF, 0x00
gdt_info: 
dw gdt_info - gdt
dw gdt, 0
[BITS 32]
protected_mode:
mov ax, 0x10
mov es, ax
mov ds, ax
mov ss, ax
call 0x11000
times (512 - ($ - start) - 2) db 0 
db 0x55, 0xAA

And minimal realization of Kernel in C:

extern "C" int kmain();
__declspec(naked) void startup()
{
    __asm {
        call kmain;
    }
}
#define VIDEO_BUF_PTR (0xb8000)
void out_str(int color, const char* ptr, unsigned int strnum)
{
    unsigned char* video_buf = (unsigned char*)VIDEO_BUF_PTR;
    video_buf += 80 * 2 * strnum;
    while (*ptr)
    {
        video_buf[0] = (unsigned char)*ptr;
        video_buf[1] = color;
        video_buf += 2;
        ptr++;
    }
}
extern "C" int kmain()
{
    const char* hello = "Welcome to HelloWorldOS (gcc edition)!";
    out_str(0x07, hello, 0);
    while (1)
    {
        __asm hlt;
    }
    return 0;
}

Compile kernel with Microsoft C complier Transaltor of boot: Yasm To get the data from PE-kernel used dumpbin and get:

As emulator use Qemu As the result I get:

Booting from Hard disk...
Boot failed: could not read the boot disk

Booting from from Floppy...

And nothing more. So why my OS doesn't work? I think that the problem is it bootloader, but I'm not sure. (I only started to learn opeation systems, so I don't know much in it). I have to run it with all my upper conditions
